Description

The AT1303 is a high efficiency current mode PWM step-up DC/DC converter with light load control for applications using battery-powered system. The device will automatically skip switching cycles under light load condition to maintain high efficiency at light load. The small MSOP-8 or TSSOP-8 packages make the AT1303 an ideal choice of DC/DC Converter for space conscious applications.
