Description

The 12A Analog Pico SlimLynxTM Open Frame power modules are non-isolated dc-dc converters that can deliver up to 12A of

output current. These modules operate over a wide range of input voltage (VIN = 3Vdc-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 12A Analog Pico SlimLynxTM Open Frame 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 37 shows

the input ripple voltage for various output voltages at 12A

of load current with 1x22 µF or 2x22 µF ceramic

capacitors and an input of 12V.

Figure 37. Input ripple voltage for various output

voltages with 1x22 µF or 2x22 µF ceramic capacitors at

the input (12A load). Input voltage is 12V (20MHz BW)

Output Filtering

These modules are designed for low output ripple voltage

and will meet the maximum output ripple specification with

3x0.047 µF ceramic and 2x47 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 38 provides output ripple

information, measured with a scope with its Bandwidth

limited to 20MHz for different external capacitance values at

various Vo and a full load current of 12A. 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, 6x47 µF or 8x47

µF ceramic capacitors at the output (12A load). Input

voltage is 12V. (20MHz BW)

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.,

UL 60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN EN 60950-

1:2006 + A11 (VDE0805 Teil 1 + A11):2009-11; EN 60950-

1:2006 + A11:2009-03.

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.

The input to these units is to be provided with a fast-acting

fuse (e.g. ABC Bussmann) with a maximum rating of 20 A in

the positive input lead.

Analog Feature Descriptions

Remote On/Off

The 12A Analog Pico SlimLynxTM Open Frame 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 diode is turned

OFF. This keeps the internal Enable signal to be pulled up by

the internal 3.3V, thus turning/keeping the module ON. When

transistor Q1 is turned ON, the internal diode conducts and

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 Q1 is in the OFF

state, the On/Off pin is pulled high, transistor Q2 is turned ON.

This pulls the internal ENABLE low and the module is OFF. To

turn the module ON, Q1 is turned ON pulling the On/Off pin

low, turning transistor Q2 OFF, which results in the PWM

Enable pin going high.

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. 41. 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

0.6V, the input voltage needs to be larger than the minimum

of 3V.

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, 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 Critical Power

technical representative for additional details.

voltage.

Output Voltage Sequencing

The power module includes a sequencing feature, EZ-

SEQUENCE that enables users to implement various types of

output voltage sequencing in their applications. This is

accomplished via an additional sequencing pin. When not

using the sequencing feature, leave it unconnected.

The voltage applied to the SEQ pin should be scaled down by

the same ratio as used to scale the output voltage down to

the reference voltage of the module. This is accomplished by

an external resistive divider connected across the

sequencing voltage before it is fed to the SEQ pin as shown

in Fig. 44. In addition, a small capacitor (suggested value

100pF) should be connected across the lower resistor R1.

For all SlimLynx modules, the minimum recommended delay

between the ON/OFF signal and the sequencing signal is

10ms to ensure that the module output is ramped up

according to the sequencing signal. This ensures that the

module soft-start routine is completed before the

sequencing signal is allowed to ramp up.

Figure 44. Circuit showing connection of the sequencing

signal to the SEQ pin.

When the scaled down sequencing voltage is applied to the

SEQ pin, the output voltage tracks this voltage until the

output reaches the set-point voltage. The final value of the

sequencing voltage must be set higher than the set-point

voltage of the module. The output voltage follows the

sequencing voltage on a one-to-one basis. By connecting

multiple modules together, multiple modules can track their

output voltages to the voltage applied on the SEQ pin.

The module’s output can track the SEQ pin signal with slopes

of up to 0.5V/msec during power-up or power-down.

To initiate simultaneous shutdown of the modules, the SEQ

pin voltage is lowered in a controlled manner. The output

voltage of the modules tracks the voltages below their set-

point voltages on a one-to-one basis. A valid input voltage

must be maintained until the tracking and output voltages

reach ground potential.

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 overtemperature threshold of 150oC(typ) is

exceeded at the thermal reference point Tref .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 Electrical Specifications table

specifies the requirements of the external SYNC signal. If the

SYNC pin is not used, the module should free run at the

default switching frequency. If synchronization is not being

used, connect the SYNC pin to GND.

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.

Recommended values of RTUNE and CTUNE for different output

capacitor combinations are given in Table 2. Table 2 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 2 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 6A to 12A step change (50% of full load),

with an input voltage of 12V.

Please contact your GE Critical Power 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.

Power Good

The module provides a Power Good (PGOOD) signal that is

implemented with an open-drain output to indicate that the

output voltage is within the regulation limits of the power

module. The PGOOD signal will be de-asserted to a low state

if any condition such as over temperature, overcurrent or

loss of regulation occurs that would result in the output

voltage going outside the specified thresholds.

The PGOOD terminal can be connected through a pullup

resistor (suggested value 100K) to a source of 5VDC or

lower.

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 47. The

preferred airflow direction for the module is in Figure 48.

The thermal reference points, Tref used in the specifications

are also shown in Figure 48. For reliable operation the

temperatures at the Q3 should not exceed 120oC and the

temperature at L1 core should not exceed 125°C. The output

power of the module should not exceed the rated power of

the module (Vo,set x Io,max).

Surface Mount Information

Pick and Place

The 12A Analog Pico SlimLynxTM Open Frame 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.

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. D

(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). The recommended linear reflow profile using Sn/Ag/Cu

solder is shown in Fig. 50. Soldering outside of the

recommended profile requires testing to verify results and

performance.

MSL Rating

The 12A Analog Pico SlimLynxTM Open Frame 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
