3 Description

The TPSM63602 synchronous buck power module

is a highly integrated 36-V, 2-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

TPSM63602 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 TPSM63602

module offers many features for robust performance:

precision enable with hysteresis for adjustable inputvoltage

UVLO, resistor-programmable switch node

slew rate for improved EMI, integrated VCC, bootstrap

and input capacitors for increased reliability and

higher density, constant switching frequency over the

full load current range for enhanced load transient

performance, and a PGOOD indicator for sequencing,

fault protection, and output voltage monitoring.
