AX7703A/B-Low Noise, Regulated Charge Pump

AX7703/A/B-Low Noise,Regulated Charge Pump DataSheet

GENERAL DESCRIPTION
The AX7703A/B is a Low noise charge pump DC/DC converter that produces a regulated 4.5V and 5V output. No external inductor is required for operation. Using three small capacitors, the AX7703A/B can deliver up to 100mA to the voltage regulated output. The AX7703A/B features very low quiescent current and high efficiency over a large portion of its load range, making this device ideal for battery-powered applications.
AX7703A/B has over current protection, short circuit protection and thermal shutdown protection capability. Internal soft-start circuitry effectively reduces the in-rush current while start-up. The AX7703A/B is available in a SOT23-6 package.
