产品概述 返回TOP
The CXUS65176 has a NMOS open-drain output pin for power good indication. When VOUT > 1.5 *VIN* 90%, the NMOS will be turned off immediately and PG pin will be pulled high by external resistor. The CXUS65176 contains an over-temperature circuit to protect the device under continuous output short circuit conditions. The device is available in a 8-pin MSOP packageThe CXUS65176 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 56μA at 8V supply and 96μA at 24V supply. The CXUS65176 can deliver 10mA output current with a voltage drop of 900mV at 24V supply.
