产品概述 返回TOP
CXSU63248 is a 1.2MHz fixed frequency, Current mode, high efficiency synchronous boost regulator that converts down to 0.9V input into up to 4V output voltage. It adopts very low Rdson N-MOS for the main switch and P-MOS for the synchronous switch, so no external Schottky didode is required, and the system efficiency is improved. It can disconnect the output during the shutdown operation. The CXSU63248 intended for systems that are typically operated from a single or dual-cell nickel-cadmium(NICd), mickel-metal hydride (NiMH), or alkaline battery.
