APW7290 Description
APW7290 operates with a constant 1.5MHz switching frequency and using the inductor current as a controlled quantity in the current mode architecture. The 3.5V to 7.2V input voltage range makes the APW7290 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable electrical devices.
