产品概述 返回TOP
CXSU63171 is a high efficiency, current‐mode control Boost DC to DC regulator with an integrated 120mΩ RDS(ON) N‐channel MOSFET. The fixed 1MHz switching frequency and internal compensation reduce external component count and save the PCB space. The build‐in internal soft start circuitry minimizes the inrush current at start‐up.
