Typical Application


The SY20183L and SY20183 are high-efficiency 2.25MHz synchronous step-down DC-DC converters capable of delivering1.5Aoutput current. SY20183/L operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
