Overview
The Texas Instruments TPSM828221SILR is a high-efficiency step-down converter MicroSiP™ power module designed for compact and efficient power management solutions. This device is part of the TPSM8282x family, which includes 1-A, 2-A, and 3-A step-down converters. The TPSM828221SILR specifically offers a 2-A output current and is housed in a 2.0-mm × 2.5-mm × 1.1-mm 10-pin μSiL package, making it ideal for applications where space is limited.
The module integrates a synchronous step-down converter and an inductor, simplifying design, reducing external components, and saving PCB area. It features a DCS-control topology for excellent load transient performance and accurate output voltage regulation.
