Description

The 7A Analog PicoDLynxIITM power modules are non-isolated dc-dc converters that can deliver up to 7A of output current. These

modules operate over a wide range of input voltage (VIN = 4.5Vdc-14.4Vdc) and provide a precisely regulated output voltage from

0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current

and over temperature protection. The module also includes the Tunable LoopTM feature that allows the user to optimize the

dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and

PWB area.

Design Considerations

Input Filtering

The 7A Analog PicoDLynxIITM module should be

connected to a low ac-impedance source. A highly

inductive source can affect the stability of the module. An

input capacitance must be placed directly adjacent to the

input pin of the module, to minimize input ripple voltage

and ensure module stability.

To minimize input voltage ripple, ceramic capacitors are

recommended at the input of the module. Figure 31

shows the input ripple voltage for various output voltages

at 7A of load current with 2x22 µF or 4x22 µF ceramic

capacitors and an input of 12V.

Input Ripple Voltage (mVp-p)

Output Voltage (Vdc)

Figure 37. Input ripple voltage for various output

voltages with 2x22 µF or 4x22 µF ceramic capacitors at

the input (7A load). Input voltage is 12V.

Output Filtering

These modules are designed for low output ripple voltage

and will meet the maximum output ripple specification with

0.1 µF ceramic and 3x22 µF ceramic capacitors at the

output of the module. However, additional output filtering

may be required by the system designer for a number of

reasons. First, there may be a need to further reduce the

output ripple and noise of the module. Second, the dynamic

response characteristics may need to be customized to a

particular load step change.

To reduce the output ripple and improve the dynamic

response to a step load change, additional capacitance at

the output can be used. Low ESR polymer and ceramic

capacitors are recommended to improve the dynamic

response of the module. Figure 32 provides output ripple

information for different external capacitance values at

various Vo and a full load current of 7A. For stable operation

of the module, limit the capacitance to less than the

maximum output capacitance as specified in the electrical

specification table. Optimal performance of the module can

be achieved by using the Tunable LoopTM feature described

later in this data sheet.

Figure 38. Output ripple voltage for various output

voltages with external 2x47 µF, 4x47 µF or 6x47 µF

ceramic capacitors at the output (7A load). Input voltage

is 12V.

Safety Considerations

For safety agency approval the power module must be

installed in compliance with the spacing and separation

requirements of the end-use safety agency standards, i.e.,

ANSI/UL 60950-1 2nd Revised October 14, 2014, CSA C22.2

No. 60950-1-07, Second Ed. + A2:2014 (MOD), DIN EN 60950-

1:2006 + A11:2009 + A1:2010 +A12:2011, + A2:2013

(VDE0805 Teil 1: 2014-08)(pending).

For the converter output to be considered meeting the

requirements of safety extra-low voltage (SELV), the input

must meet SELV requirements. The power module has

extra-low voltage (ELV) outputs when all inputs are ELV.

An external 20A Littelfuse 456 series fast-acting fuse or

equivalent is recommended on the ungrounded input lead.

Analog Feature Descriptions

Remote On/Off

The 7A Analog PicoDLynxIITM power modules feature an

On/Off pin for remote On/Off operation. Two On/Off logic

options are available. In the Positive Logic On/Off option,

(device code suffix “4” – see Ordering Information), the

module turns ON during a logic High on the On/Off pin and

turns OFF during a logic Low. With the Negative Logic

On/Off option, (no device code suffix, see Ordering

Information), the module turns OFF during logic High and ON

during logic Low. The On/Off signal should be always

referenced to ground. For either On/Off logic option, leaving

the On/Off pin disconnected will turn the module ON when

input voltage is present.

For positive logic modules, the circuit configuration for using

the On/Off pin is shown in Figure 39. When the external

transistor Q1 is in the OFF state, the internal PWM #Enable is

pulled up internally, thus turning the module ON. When

transistor Q1 is turned ON, the On/Off pin is pulled low, and

consequently the internal PWM Enable signal is pulled low

and the module is OFF.

For negative logic On/Off modules, the circuit configuration

is shown in Fig. 40. The On/Off pin should be pulled high with

an external pull-up resistor. When transistor Q2 is in the OFF

state, the On/Off pin is pulled high, which pulls the internal

ENABLE# High and the module is OFF. To turn the module

ON, Q2 is turned ON pulling the On/Off pin low resulting in

the PWM ENABLE# pin going Low. The typical voltage

allowed on the On/Off pin is 7V. If Vin is used as a source,

then a suitable external resistor R1 must be used to ensure

that the voltage on the On/Off pin does not exceed 7V.

logic.

logic.

Monotonic Start-up and Shutdown

The module has monotonic start-up and shutdown behavior

for any combination of rated input voltage, output current

and operating temperature range.

Startup into Pre-biased Output

The module can start into a prebiased output as long as the

prebias voltage is 0.5V less than the set output voltage.

Analog Output Voltage Programming

The output voltage of the module is programmable to any

voltage from 0.6dc to 5.5Vdc by connecting a resistor

between the Trim and SIG_GND pins of the module. Certain

restrictions apply on the output voltage set point depending

on the input voltage. These are shown in the Output Voltage

vs. Input Voltage Set Point Area plot in Fig. 35. The Upper

Limit curve shows that for output voltages lower than 1V,

the input voltage must be lower than the maximum of

14.4V. The Lower Limit curve shows that for output voltages

higher than 3.3V, the input voltage needs to be higher than

the minimum of 4.5V.

Remote Sense

The power module has a Remote Sense feature to minimize

the effects of distribution losses by regulating the voltage

between the sense pins (VS+ and VS-). The voltage drop

between the sense pins and the VOUT and GND pins of the

module should not exceed 0.5V.

Analog Voltage Margining

Output voltage margining can be implemented in the

module by connecting a resistor, Rmargin-up, from the Trim pin

to the ground pin for margining-up the output voltage and

by connecting a resistor, Rmargin-down, from the Trim pin to

output pin for margining-down. Figure 43 shows the circuit

configuration for output voltage margining. The POL

Programming Tool or Power Module Wizard(PMW), available

at www.gecriticalpower.com under the Downloads section,

also calculates the values of Rmargin-up and Rmargin-down for a

specific output voltage and % margin. Please consult your

local GE technical representative for additional details.

Overcurrent Protection

To provide protection in a fault (output overload) condition,

the unit is equipped with internal current-limiting circuitry

and can endure current limiting continuously. At the point of

current-limit inception, the unit enters hiccup mode. The unit

operates normally once the output current is brought back

into its specified range.

Overtemperature Protection

To provide protection in a fault condition, the unit is

equipped with a thermal shutdown circuit. The unit will shut

down if the over-temperature threshold of 120°C (typ) is

exceeded at the thermal reference point Tref. Please refer to

Electrical characteristic table, over-temperature section on

page 5. Once the unit goes into thermal shutdown it will

then wait to cool before attempting to restart.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout limit,

the module operation is disabled. The module will begin to

operate at an input voltage above the undervoltage lockout

turn-on threshold.

Synchronization

The module switching frequency can be synchronized to a

signal with an external frequency within a specified range.

Synchronization can be done by using the external signal

applied to the SYNC pin of the module as shown in Fig. 45,

with the converter being synchronized by the rising edge of

the external signal. The module switches at half the SYNC

frequency. The Electrical Specifications table specifies the

requirements of the external SYNC signal. If the SYNC pin is

not used, the module will free run at the default switching

frequency. If synchronization is not being used, connect

the SYNC pin to Sig_GND.

Dual Layout

Identical dimensions and pin layout of Analog and Digital

PicoDLynxII modules permit migration from one to the other

without needing to change the layout. In both cases the trim

resistor is connected between trim and signal ground. The

output of the analog module cannot be trimmed down to

0.51V

Tunable LoopTM

The module has a feature that optimizes transient response

of the module called Tunable LoopTM.

External capacitors are usually added to the output of the

module for two reasons: to reduce output ripple and noise

(see Figure 38) and to reduce output voltage deviations from

the steady-state value in the presence of dynamic load

current changes. Adding external capacitance however

affects the voltage control loop of the module, typically

causing the loop to slow down with sluggish response. Larger

values of external capacitance could also cause the module

to become unstable.

The Tunable LoopTM allows the user to externally adjust the

voltage control loop to match the filter network connected to

the output of the module. The Tunable LoopTM is implemented

by connecting a series R-C between the VS+ and TRIM pins of

the module, as shown in Fig. 46. This R-C allows the user to

externally adjust the voltage loop feedback compensation of

the module.

Figure. 46. Circuit diagram showing connection of RTUME

and CTUNE to tune the control loop of the module.

Recommended values of RTUNE and CTUNE for different output

capacitor combinations are given in Tables 2 and 3. Table 3

shows the recommended values of RTUNE and CTUNE for

different values of ceramic output capacitors up to 1000uF

that might be needed for an application to meet output

ripple and noise requirements. Selecting RTUNE and CTUNE

according to Table 3 will ensure stable operation of the

module.

In applications with tight output voltage limits in the

presence of dynamic current loading, additional output

capacitance will be required. Table 3 lists recommended

values of RTUNE and CTUNE in order to meet 2% output

voltage deviation limits for some common output voltages

in the presence of a 3.5A to 7A step change (50% of full

load), with an input voltage of 12V.

Please contact your GE technical representative to obtain

more details of this feature as well as for guidelines on how

to select the right value of external R-C to tune the module

for best transient performance and stable operation for

other output capacitance values.

Thermal Considerations

Power modules operate in a variety of thermal

environments; however, sufficient cooling should always be

provided to help ensure reliable operation.

Considerations include ambient temperature, airflow,

module power dissipation, and the need for increased

reliability. A reduction in the operating temperature of the

module will result in an increase in reliability. The thermal

data presented here is based on physical measurements

taken in a wind tunnel. The test set-up is shown in Figure

48. The preferred airflow direction for the module is in

Shock and Vibration

The ruggedized (-D version) of the modules are designed to withstand elevated levels of shock and vibration to be able to operate

in harsh environments. The ruggedized modules have been successfully tested to the following conditions:

Non operating random vibration:

Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms

(Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes.

Operating shock to 40G per Mil Std. 810G, Method 516.4 Procedure I:

The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock

impulse characteristics as follows:

All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes.

Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of

40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen

shocks.

Operating vibration per Mil Std 810G, Method 514.5 Procedure I:

The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810G, Method 514.5, and

Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 4 and Table 5 for all axes. Full compliance with

performance specifications was required during the performance test. No damage was allowed to the module and full compliance

to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD-

810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and

endurance levels shown in Table 4 and Table 5 for all axes. The performance test has been split, with one half accomplished before

the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16

minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours

minimum per axis.

Surface Mount Information

Pick and Place

The 7A Analog PicoDLynxIITM modules use an open frame

construction and are designed for a fully automated

assembly process. The modules are fitted with a label

designed to provide a large surface area for pick and place

operations. The label meets all the requirements for surface

mount processing, as well as safety standards, and is able

to withstand reflow temperatures of up to 300oC. The label

also carries product information such as product code,

serial number and the location of manufacture.

Nozzle Recommendations

The module weight has been kept to a minimum by using

open frame construction. Variables such as nozzle size, tip

style, vacuum pressure and placement speed should be

considered to optimize this process. The minimum

recommended inside nozzle diameter for reliable operation

is 3mm. The maximum nozzle outer diameter, which will

safely fit within the allowable component spacing, is 7 mm.

Bottom Side / First Side Assembly

This module is not recommended for assembly on the

bottom side of a customer board. If such an assembly is

attempted, components may fall off the module during the

second reflow process.

Lead Free Soldering

The modules are lead-free (Pb-free) and RoHS compliant

and fully compatible in a Pb-free soldering process. Failure

to observe the instructions below may result in the failure of

or cause damage to the modules and can adversely affect

long-term reliability.

Pb-free Reflow Profile

Power Systems will comply with J-STD-020 Rev. C

(Moisture/Reflow Sensitivity Classification for Nonhermetic

Solid State Surface Mount Devices) for both Pb-free solder

profiles and MSL classification procedures. This standard

provides a recommended forced-air-convection reflow

profile based on the volume and thickness of the package

(table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu

(SAC). For questions regarding Land grid array(LGA)

soldering, solder volume; please contact GE for special

manufacturing process instructions. The recommended

linear reflow profile using Sn/Ag/Cu solder is shown in Fig.

44. Soldering outside of the recommended profile requires

testing to verify results and performance.

MSL Rating

The 7A Analog PicoDLynxIITM modules have a MSL rating of

2A.

Storage and Handling

The recommended storage environment and handling

procedures for moisture-sensitive surface mount packages

is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping

and Use of Moisture/Reflow Sensitive Surface Mount

Devices). Moisture barrier bags (MBB) with desiccant are

required for MSL ratings of 2 or greater. These sealed

packages should not be broken until time of use. Once the

original package is broken, the floor life of the product at

conditions of  30°C and 60% relative humidity varies

according to the MSL rating (see J-STD-033A). The shelf life

for dry packed SMT packages will be a minimum of 12

months from the bag seal date, when stored at the following

conditions: < 40° C, < 90% relative humidity.

Figure 50. Recommended linear reflow profile using

Sn/Ag/Cu solder.

Post Solder Cleaning and Drying Considerations

Post solder cleaning is usually the final circuit-board

assembly process prior to electrical board testing. The result

of inadequate cleaning and drying can affect both the

reliability of a power module and the testability of the

finished circuit-board assembly. For guidance on

appropriate soldering, cleaning and drying procedures, refer

to Board Mounted Power Modules: Soldering and Cleaning
