The device provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components and online design support through WEBENCH, the LM2734-Q1 regulator is easy to use. The ability to drive 1-A loads with an internal 300-mΩ NMOS switch using state-ofthe-art 0.5-µm BiCMOS technology results in the best power density available. The world-class control circuitry allows for on-times as low as 13 ns, thus supporting exceptionally high-frequency convers...
