3 Description
The LMR120xx regulator is a monolithic, high frequency, PWM step-down DC/DC converter in a 10pin WSON package. 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...
