SY20018I
SY20018I is 1A Synchronous Step-Down Regulator manufactured by Silergy.
High-Efficiency, 1.5MHz,1A Synchronous Step-Down Regulator
General Description
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 conduction loss. The 1.5MHz switching frequency allows for low output-voltage ripple, as well as small external inductor and capacitor values.
The SY20018I is highly integrated, so only the input and output capacitors, inductor, and feedback resistors need to be selected for the targeted application...
