3 Description

Deriving from a family of synchronous buck modules,

the TPSM63610 is a highly integrated 36-V, 8-A

DC/DC solution that combines power MOSFETs, a

shielded inductor, and passives in an Enhanced

HotRod? QFN package. The module has VIN and

VOUT pins located at the corners of the package

for optimized input and output capacitor 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 20 V, the

TPSM63610 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 TPSM63610

module offers many features for robust performance:

precision enable with hysteresis for adjustable inputvoltage

UVLO, resistor-programmable switch node

slew rate and spread spectrum and spread spectrum

option for improved EMI. Along with integrated VCC,

bootstrap and input capacitors for increased reliability

and higher density. The module can be configured

for constant switching frequency over the full load

current range (FPWM), or variable frequency (PFM)

for higher light load efficiency. Including a PGOOD

indicator for sequencing, fault protection, and output

voltage monitoring.
