8.1 Application Information

The LMR10530 regulator is a monolithic, high frequency, PWM step-down DC/DC converter available in a 10-pin 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 LMR10530 is easy to use. Switching frequency is internally set to 1.5 MHz or 3 MHz, allowing the use of extremely small surface mount inductors and capacitors. Even though the operating frequency is high, efficiencies up to 93% are easy to achieve.
