3 Description

The TPSM8282x device family consists of a 1-A, 2-

modules optimized for small solution size and high

efficiency.

The power modules integrate a synchronous step-

down converter and an inductor to simplify design,

reduce external components and save PCB area.

The low profile and compact solution is suitable

for automated assembly by standard surface mount

equipment. To maximize efficiency, the converter

operates in PWM mode with a nominal switching

frequency of 4MHz and automatically enters Power

Save Mode operation at light load currents.

In Power Save Mode, the device operates with

typically 4-µA quiescent current. Using the DCS-

Control topology, the device achieves excellent

load transient performance and accurate output

voltage regulation. The EN and PG pins, which

support sequencing configurations, bring a flexible

system design. An integrated soft startup reduces

the inrush current required from the input supply.

Over temperature protection and hiccup short circuit

protection deliver a robust and reliable solution.
