SY20118A
Description
The SY20118A high-efficiency 1MHz synchronous step-down DC/DC regulator operates over a wide input voltage range of 2.5V to 5.5V, and can deliver an output current up to 4A with a low quiescent current of 55µA. It integrates a main switch and a synchronous switch with very low RDS(ON) to minimize conduction loss.
