SY20018I - 1A Synchronous Step-Down Regulator
The SY20018I high-efficiency 1.5MHz 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 1A with a low quiescent current of 50µA.
It integrates a main switch and a synchronous switch with very low RDS(ON) to minimize
