DESCRIPTION
The VDRM series of the MagI³C Power Module family
provide a fully integrated DC-DC power supply
including the buck switching regulator and inductor in
a package.
The WPMDH1200601 offers high efficiency and
delivers up to 5A of output current. It operates from
6V input voltage up to 36V. It is designed for fast

circuitry to guard against thermal overstress and
electrical damage featuring thermal shut-down, over-
current, short-circuit, overvoltage and under-voltage
protections.

PIN DESCRIPTION
The supply input pin is a terminal for an unregulated input voltage source. It is
required to place the input capacitor nearby the VIN pin and PGND.
The Sync Input pin allows to synchronize the PWM operating frequency to an
external frequency source. Apply a CMOS logic level square wave with a
frequency between 650 kHz and 950 kHz. When not using synchronization
connect to ground. The module free running PWM frequency is 812kHz (typical).
The enable input pin is internally connected to the precision enable comparator
and the rising threshold is at 1.18V. Maximum recommended input level is 6.5V.
The analog ground pin is the reference point for all stated voltages and must be
connected to PGND.
The feedback pin is internally connected to the regulation circuitry, the over-
voltage and short-circuit comparators. The regulation reference point is 0.796V
at this input pin. Connect the feedback resistor divider between the output and
AGND to set the output voltage.
The Soft-Start and Tracking pin is to extend the 1.6ms internal soft-start.
Connect an external soft start capacitor. For tracking connect to an external
resistive divider connected to a higher priority supply rail.
The output voltage pin is connected to the internal inductor. For the best stability
and operation connect the output capacitor between this pin and PGND.
Exposed Pad – Main node for switch current of internal LS-MOSFET. Used as
heat sink for power dissipation during operation. Must be electrically connected
to pin 4.

NOTES
(1)
The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test
method is per JESD-22-114.
(2)
(3)
JEDEC J-STD020
Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are
guaranteed through correlation using Statistical Quality Control (SQC) methods.
(4)
Typical numbers are valid at 25°C ambient temperature and represent statistically the utmost probability
assuming the Gaussian distribution.
(5)
(6)
Depending on heat sink design, number of PCB layers, copper thickness and air flow.
Measured on a 3.5” x 3.5” four layer board, with 104µm (3 ounce) copper on outer layers and 70µm (2
ounce) copper on inner layers, sixty 10 mil thermal vias, no air flow, and 1W power dissipation
