It contains 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 LMR12015/20 is easy to use. The ability to drive 1.5A or 2-A loads, with an internal 150-mΩ NMOS switch results in the best power density available. The control circuitry allo...
