Description
The 40A Analog MegaDLynxTM power modules are non-isolated dc-dc converters that can deliver up to 40A 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 2.0Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and
overtemperature protection. The module also includes the Tunable Loop TM 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

6x47uF Ext Cap
Input Filtering
The 40A Analog MegaDLynxTM 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 19 shows
the input ripple voltage for various output voltages at 40A
of load current with 4x22 µF, 6x22µF or 8x22uF ceramic
capacitors and an input of 12V.

Output Filtering
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 with a maximum rating of 30A, 100V (for example,
Littlefuse 456 series) in the positive input lead.
These modules are designed for low output ripple voltage
and will meet the maximum output ripple specification with
0.1 µF ceramic and 47 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 20 provides output ripple
information for different external capacitance values at
various Vo and a full load current of 40A. 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.

40A Analog MegaDLynxTM: Non-Isolated DC-DC Power Modules
4.5Vdc –14.4Vdc input; 0.6Vdc to 2.0Vdc output; 40A Output Current
Analog Feature Descriptions
Monotonic Start-up and Shutdown
Remote On/Off
The module has monotonic start-up and shutdown behavior
for any combination of rated input voltage, output current
and operating temperature range.
The 40A Analog MegaDLynxTM 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 21.
For negative logic On/Off modules, the circuit configuration is
shown in Fig. 22..
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 2.0Vdc 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. 23. The Upper
Limit curve shows that for output voltages lower than 0.8V,
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 4.5V.

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. 26. In addition, a small capacitor (suggested value
100pF) should be connected across the lower resistor R1.
For all DLynx 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.
DLynx Module
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 25 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at www.GEpower.com under

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 setpoint voltages on a one-to-one basis. A valid input voltage
must be maintained until the tracking and output voltages
reach ground potential.

meet the required transient specification. For providing
better noise immunity, we recommend that RTUNE value
to be greater than 300Ω.
Some special considerations apply for design of converters
in parallel operation:
•
When sizing the number of modules required for
parallel operation, take note of the fact that current
sharing has some tolerance. In addition, under
transient conditions such as a dynamic load change
and during startup, all converter output currents will
not be equal. To allow for such variation and avoid the
likelihood of a converter shutting off due to a current
overload, the total capacity of the paralleled system
should be no more than 90% of the sum of the
individual converters. As an example, for a system of
four MegaDLynxTM converters in parallel, the total
current drawn should be less that 90% of (3 x 40A), i.e.
less than 108 A.
•
All modules should be turned ON and OFF together. This
is so that all modules come up at the same time
avoiding the problem of one converter sourcing current
into the other leading to an overcurrent trip condition.
To ensure that all modules come up simultaneously, the
on/off pins of all paralleled converters should be tied
together and the converters enabled and disabled
using the on/off pin. Note that this means that
converters in parallel cannot be digitally turned ON as
that does not ensure that all modules being paralleled
turn on at the same time.
•
If digital trimming is used to adjust the overall output
voltage, the adjustments need to be made in a series of
small steps to avoid shutting down the output. Each
step should be no more than 20mV for each module.
For example, to adjust the overall output voltage in a
setup with two modules (A and B) in parallel from 1V to
1.1V, module A would be adjusted from 1.0 to 1.02V
followed by module B from 1.0 to 1.02V, then each
module in sequence from 1.02 to 1.04V and so on until
the final output voltage of 1.1V is reached.
•
If the Sequencing function is being used to start-up and
shut down modules and the module is being held to 0V
by the tracking signal then there may be small
deviations on the module output. This is due to
controller duty cycle limitations encountered in trying
to hold the voltage down near 0V.
•
The share bus is not designed for redundant operation
and the system will be non-functional upon failure of
one of the units when multiple units are in parallel. In
particular, if one of the converters shuts down during
operation, the other converters may also shut down
due to their outputs hitting current limit. In such a
situation, unless a coordinated restart is ensured, the
system may never properly restart since different
converters will try to restart at different times causing
an overload condition and subsequent shutdown. This
situation can be avoided by having an external output
voltage monitor circuit that detects a shutdown
condition and forces all converters to shut down and
restart together.
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. 27,
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.

Active Load Sharing (-P Option)
For additional power requirements, the Mega DLynxTM
power module is also equipped with paralleling capability.
Up to five modules can be configured in parallel, with active
load sharing.
To implement paralleling, the following conditions must be
satisfied.
•
All modules connected in parallel must be frequency
synchronized where they are switching at the same
frequency. This is done by using the SYNC function of
the module and connecting to an external frequency
source. Modules can be interleaved to reduce input
ripple/filtering requirements.
•
The share pins of all units in parallel must be connected
together. The path of these connections should be as
direct as possible.
•
The remote sense connections to all modules should be
made that to the same points for the output, i.e. all VS+
and VS- terminals for all modules are connected to the
power bus at the same points.
•
For converters operating in parallel, tunable loop
components “RTUNE” and “CTUNE” must be selected to

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 default value of PGOOD ON thresholds are set at ±8% of
the nominal Vset value, and PGOOD OFF thresholds are set
at ±10% of the nominal Vset. For example, if the nominal
voltage (Vset) is set at 1.0V, then the PGOOD ON thresholds
will be active anytime the output voltage is between 0.92V
and 1.08V, and PGOOD OFF thresholds are active at 0.90V
and 1.10V respectively.
The PGOOD terminal can be connected through a pull-up
resistor (suggested value 100K) to a source of 5VDC or
lower.
Dual Layout
Identical dimensions and pin layout of Analog and Digital
MegaDLynx 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.
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
and to reduce output voltage deviations from the steadystate 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. 28. This R-C
allows the user to externally adjust the voltage loop
feedback compensation of the module.

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
29. The preferred airflow direction for the module is in
Figure 30.

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 20A to 40A step change (50% of full
load), with an input voltage of 12V.

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 1 and Table 2 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-STD810, 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.

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 longterm reliability.
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.

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).
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 42). 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. 31. Soldering outside of the recommended
profile requires testing to verify results and performance.
MSL Rating
The 40A Analog MegaDLynxTM 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
