目录7.相关产品 产品概述 返回TOP The CXUS65177 is a high-voltage switched-capacitor charge pump that provides the regulated output voltage of 1.5x input voltage. Input voltages ranging from 8V to 24V can be converted into a 12V to 36V output supply. The device is ideal for battery-powered conversion applications in notebook computers with a typical operating current of 150μA at 8V supply and 190μA at 24V supply. The CXUS65177 has a NMOS open-drain output pin for power good indication. When VOUT > 1.5 x VIN x 90%, the NMOS will be turned off immediately and PG pin will be pulled high by external resistor. The CXUS65177 contains an embedded 12-V LDO to provide the supply voltage to the drivers controlled by ON signals. The discharging networks are connected to the 22Ω resistor to shut down the low-voltage system while control input signals ON are not ready. The CXUS65177 contains an over-temperature circuit to protect the device under continuous output short circuit conditions. The CXUS65177 is available in TQFN3X3-20 package (thermal pad included).产品特点 返回TOP „ Input Range: 8V to 24V „ Output Range: 12V to 36V „ 150μA Quiescent Current at 8V Supply Voltage and 190μA Quiescent Current at 24V Supply Voltage „ ±3% Regulated Output „ Power Good Function „ Power Good of Open Drain (Monitor AC VIN Only) „ Embedded a 12-V LDO „ 4 Control Signal Inputs „ 4 12V-Drivers for external NMOS switches „ 4 Discharging Networks for 22Ω „ Over-Temperature Protection „ Output Short Circuit Protection „ TQFN3X3-20 Package 应用范围 返回TOP „ Notebook Computers 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 产品封装图 返回TOP
