It 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, the LMR10520 is easy to use. The ability to drive 2-A loads with an internal 150-mΩ PMOS switch results in the best power density available. The world-class control circuitry allows ontimes as low as 30 ns, thus supporting exceptionally high frequency conversion over the entire 3-V to 5.5.
