LM26420 Overview
The LM26420 regulator is a monolithic, highefficiency dual PWM step-down DC/DC converter. This device has the ability to drive two 2-A loads with an internal 75-mΩ PMOS top switch and an internal 50-mΩ NMOS bottom switch using state-of-the-art BICMOS technology results in the best power density available. The world-class control circuitry allow on times as low as 30 ns, thus supporting exceptionally high-frequency...
