Description
The 6A Analog SlimLynxTM Encapsulated power modules are non-isolated dc-dc converters that can deliver up to 6A 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 in the controller. 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.

6A Analog SlimLynxTM Encapsulated: Non-Isolated DC-DC Power Modules

Design Considerations
Input Filtering
The 6A Analog SlimLynxTM Encapsulated 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 6A
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 (6A load). Input voltage is 12V. Scope
Bandwidth at 20MHz
Output Filtering
These modules are designed for low output ripple voltage
and will meet the maximum output ripple specification with
suggested 2x0.047µF+1x1uF ceramic decoupling capacitors
and 1x47 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 6A. 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 (6A load). Input
voltage is 12V. Sope Bandwidth at 20MHz
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 with a fast
acting fuse (e.g. ABC Bussmann) with a maximum rating of
20 A in the positive input lead.

Remote On/Off
The 6A Analog SlimLynxTM Encapsulated 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 Q2 is in the OFF state, the internal transistor Q7 is
turned ON, which turn Q3 OFF which keeps Q6 OFF and Q5
OFF. This allows the internal PWM #Enable signal to be
pulled up by the internal 3.3V, thus turning the module ON.
When transistor Q2 is turned ON, the On/Off pin is pulled
low, which turns Q7 OFF which turns Q3, Q6 and Q5 ON and
the internal PWM #Enable signal is pulled low and the
module is OFF. A suggested value for Rpullup is 20kΩ.
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 (suggested value for the 3V to
14V input range is 20Kohms). When transistor Q2 is in the
OFF state, the On/Off pin is pulled high, transistor Q3 is
turned ON. This turns Q6 ON, followed by Q5 turning ON
which pulls the internal ENABLE low and the module is OFF.
To turn the module ON, Q2 is turned ON pulling the On/Off
pin low, turning transistor Q3 OFF, which keeps Q6 and Q5
OFF resulting in the PWM Enable pin going high.

logic.
Figure 40. Circuit configuration for using negative On/Off
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.

Without an external resistor between Trim and SIG_GND pins,

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.
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
http://www.geindustrial.com/products/embedded-power,
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.

signal to the SEQ pin.

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.

Figure 45. External source connections to synchronize
switching frequency of the module.
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 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 3A to 6A 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.

Surface Mount Information
Pick and Place
The 6A Analog SlimLynxTM Encapsulated modules use an
Encapsulated 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
Encapsulated 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
The encapsulated SlimLynx product can be assembled on
the bottom side of a customer board. The surface tension of
the solder connections between the customer board and the
module are sufficient to hold the module during the top side
reflow process. No additional glue or adhesive is required.
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 6A Analog SlimLynxTM Encapsulated modules have a MSL
rating of 3.
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 49. 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
Application Note (AN04-001).
