General Description
The G5910 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 G5910 can deliver up to 90mA (@VIN=3V) to the voltage-regulated output. The G5910 features high efficiency over a large portion of its load range making this device ideal for battery-powered applications. The combination of few external compo-nents and small package size keeps the total con-verter board area to a minimum in space-restricted applications. The G5910 contains a thermal manage-ment circuit to protect the device under continuousoutput short circuit conditions.
The G5910 is available in a surface mount TDFN2X2-6, SOT-23-6 and TSOT-23-6 package.
