Overview
The TPS82140SILR is a 17-V input, 2-A synchronous step-down converter MicroSiP™ power module produced by Texas Instruments. This module is optimized for small solution size and high efficiency, integrating a synchronous step-down converter and an inductor to simplify design, reduce external components, and save PCB area. The compact 3.0-mm x 2.8-mm x 1.5-mm MicroSiP™ package makes it suitable for automated assembly by standard surface mount equipment. The converter operates in PWM mode with a nominal switching frequency of 2.0MHz and automatically enters Power Save Mode at light load currents to maximize efficiency.
