电荷泵,带关断的开关电容器电压逆变器,50 mA,35 kHz

Favorite

概览

NCP1729 是一款 CMOS 电荷泵电压逆变器,适用于基于 1.15 V 至 5.5 V 输入电压范围的运行,输出电流能力超过 50 mA。运行电流耗量仅为 122 µA,提供节电关断输入,将该电流进一步降至仅为 0.4 µA。该器件包含一个 35 kHz 振荡器可驱动四个低电阻 MOSFET 开关,产生 26 Ω 的低输出电阻,以及 99% 的电压转换能效。此器件仅需两个外部 3.3µF 即可成为一个完整逆变器,是多种电池供电和板级应用的理想方案。NCP1729 采用节省空间的 TSOP-6 (SOT-23-6) 封装。
