3 Description

The TPS82140 is a 17-V input 2-A step-down

converter MicroSiP™ power module optimized for

small solution size and high efficiency. The module

integrates 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

2.0MHz and automatically enters Power Save Mode

operation at light load currents. In Power Save Mode,

the device operates with typically 20-μA quiescent

current. Using the DCS-Control™ topology, the

device achieves excellent load transient performance

and accurate output voltage regulation.
