3 Description

Deriving from a family of synchronous buck modules,

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

DC/DC design 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 design 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

device offers many features for robust performance:

precision enable with hysteresis for adjustable

input-voltage UVLO, resistor-programmable switch

node slew rate and spread spectrum for improved

EMI. Along with integrated VCC, bootstrap and

input capacitors for increased reliability and higher

density. The device 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.
