Overview
The TPSM828212SILR is a high-efficiency step-down converter MicroSiP™ power module from Texas Instruments. This device is part of the TPSM8282x family, which includes 1-A, 2-A, and 3-A step-down converters optimized for small solution size and high efficiency. The module integrates a synchronous step-down converter and an inductor, simplifying design, reducing external components, and saving PCB area. It is available in two versions: one with an automatically entered power save mode for high efficiency at light loads, and another with forced-PWM for continuous conduction mode to minimize output ripple.
