Overview
The TPS82150SILR is a 17-V input, 1-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 device operates in PWM mode with a nominal switching frequency of 2.0 MHz and automatically enters Power Save Mode at light load currents, ensuring high efficiency over the entire load current range. The TPS82150SILR features the DCS-Control™ topology, which combines the advantages of hysteretic and voltage mode control, providing excellent load transient performance and accurate output voltage regulation.
