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 LMR10515 is easy to use. The ability to drive 1.5-A loads with an internal 130-mΩ PMOS switch results in the best power density available. The world-class control circuitry allows on-times as low as 30ns, thus ...
