CXSU63248是一款1.2兆赫固定频率、电流模式、高效率的同步升压调节器，可将0.9伏的输入电压转换为4伏的输出电压。它采用极低的Rdson N-MOS作为主开关，P-MOS作为同步开关，不需要外加肖特基二极管，提高了系统效率。它可以在关机操作期间断开输出。CXSU63248适用于通常由单电池或双电池镍镉（NICd）、米克尔金属氢化物（NiMH）或碱性电池供电的系统。

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.
