TPSM82912 Overview
The TPSM8291x devices are a family of highefficiency, low-noise and low-ripple current mode synchronous buck power modules. The devices are ideal for noise sensitive applications that would normally use an LDO for post regulation such as high-speed ADCs, clock and jitter cleaner, serializer, de-serializer, and radar applications. The devices operate at a fixed switching frequency of 2.2 MHz or 1 MHz and can be...
