AIC1576 - Step-Down DC/DC Controller
The AIC1576 is a high performance step-down DC/DC controller, designed to drive an external P-channel MOSFET to generate programmable output voltages.
Two main schemes of Pulse-Skipping and Pulse-Frequency Modulation are employed to maintain low quiescent current and high conversion efficiency under
