TPSM82810 - Texas Instruments

TPSM82810 synchronous step-down DC/DC power module

TPSM8281x is a family of pin-to-pin 3-A and 4-A compatible high efficiency and easy to use synchronous step-down DC/DC power modules with integrated inductors. They are based on a fixedfrequency peak current-mode control topology. They are used in telecommunication, test and measurement, and medical applications with high power density and ease of use requi.
