3 Description

The TPSM63603 synchronous buck power module

is a highly integrated 36-V, 3-A DC/DC solution that

combines power MOSFETs, a shielded inductor, and

passives in an Enhanced HotRod™ QFN package.

The module has pins for VIN and VOUT located at the

corners of the package for optimized input and output

capacitor layout placement. Four larger thermal pads

beneath the module enable a simple layout and easy

handling in manufacturing.

With an output voltage from 1 V to 16 V, the

TPSM63603 is designed to quickly and easily

implement a low-EMI design in a small PCB footprint.

The total solution requires as few as four external

components and eliminates the magnetics and

compensation part selection from the design process.

Although designed for small size and simplicity

in space-constrained applications, the TPSM63603

module offers many features for robust performance:

precision enable with hysteresis for adjustable inputvoltage

UVLO, resistor-programmable switch node

slew rate and spread spectrum option for improved

EMI, integrated VCC, bootstrap and input capacitors

for increased reliability and higher density, constant

switching frequency over the full load current range,

and a PGOOD indicator for sequencing, fault

protection, and output voltage monitoring.
