The RM517 is a CMOS-based low-voltage step-down DC/DC module that achieves high efficiency by ultralow quiescent current (IQ = 0.3 µA) and VFM (maximum switching frequency of 1 MHz) control. Since the RM517 has a built-in inductor and the package is 3.0 (mm) x 2.4 (mm) x 0.8 (mm), QFN2430-8, it is suitable for high density mounting on board.
