   产品概述 返回TOP39B嘉泰姆

The CXUS65173 Charge-Pump is a switched-capacitor voltage converter that delivers a regulated output. The external inductor is not required for operation. Using small capacitors, the CXUS65173 can deliver up to 90mA (@VIN=3V) to the voltage-regulated output. The CXUS65173 features high efficiency over a large portion of its load range making this device ideal for battery-powered applications. The combination of few external components and small package size keeps the total converter board area to a minimum in space-restricted applications. The CXUS65173 contains a thermal management circuit to protect the device under continuous output short circuit conditions. The CXUS65173is available in a surface mount TDFN2X2-6, SOT-23-6 and TSOT-23-6 package
