TPSM82903 Overview
The TPSM82903 is a highly efficient, small, and flexible synchronous step-down DC-DC converter MicroSiP package module that is easy to use. A selectable switching frequency of 2.5 MHz or 1.0 MHz allows the use of small ponents and provides fast transient response. The device supports high VOUT accuracy of ± 1% with the DCS-Control topology.
