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.
