Description
The 2 × 12A Analog Dual MicroDlynxTM power modules are non-isolated dc-dc converters that can deliver up to 2 × 12A of output
current. These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14.4Vdc) and provide precisely regulated output
voltages 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.

The2 × 12A Analog Dual MicroDlynxTM 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

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 22 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.
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 extralow 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 (voltage rating 125Vac) in
the positive input lead. (Littelfuse 456 Series or equivalent)
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 for
different external capacitance values at various Vo and a full
load current of2 x 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.

Analog Feature Descriptions
Output 1
Remote On/Off
The2 × 12A Analog Dual MicroDlynxTM 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. For negative logic On/Off
modules, the circuit configuration is shown in Fig. 40.

Startup into Pre-biased Output
The module can start into a prebiased output on either or
both outputs as long as the prebias voltage is 0.5V less than
the set output voltage.
Analog Output Voltage Programming
The output voltage of each output of the module shall be
programmable to any voltage from 0.6dc to 5.5Vdc by
connecting a resistor between the 2 Trims 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. 1. The Upper Limit curve shows that for output
voltages lower than 1V, the input voltage must be lower than
the maximum of 14.4V. If the module can operate at 14.4V
below 1V then that is preferable over the existing upper
curve. 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 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-) for each of the 2 outputs. The
voltage drop between the sense pins and the VOUT and GND
pins of the module should not exceed 0.5V. If there is an
inductor being used on the module output, then the tunable
loop feature of the module should be used to ensure module
stability with the proposed sense point location. If the
simulation tools and loop feature of the module are not being
used, then the remote sense should always be connected
before the inductor. The sense trace should also be kept away
from potentially noisy areas of the board

connecting a resistor, Rmargin-down, from the Trim pin to output
pin for margining-down.
Figure 43 shows the circuit

Overcurrent Protection
To provide protection in a fault (output overload) condition,
the unit is equipped with internal current-limiting circuitry on
both outputs 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 135oC(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.
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. 47. This R-C allows the user to
externally adjust the voltage loop feedback compensation of
the module.

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

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

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 49. The preferred
airflow direction for the module is in Figure 50.
The thermal reference points, Tref used in the specifications are
also shown in Figure 50. For reliable operation the
temperatures at these points should not exceed 135oC. The
output power of the module should not exceed the rated
power of the module (Vo,set x Io,max).
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-Mounted
Power Modules” for a detailed discussion of thermal aspects
including maximum device temperatures.

Surface Mount Information
Pick and Place
The2 × 12A Analog Dual MicroDlynxTM 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.
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.
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.

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).
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
The2 x 12A Analog Dual MicroDlynxTM 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
