3 Description
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. The ability to drive 3-A loads with an internal 56-mΩ PMOS switch using state-of-the-art 0.5-µm Bi
CMOS technology results in the best power density available. The control circuitry allows on-times as low as 30 ns, thus supporting exceptionally highfrequency conversion over the entire 3-V to 5.5-V input operating range down to the minimum output...
