SY20149A1
Description
SY20149A1 is a high efficiency 1.5MHz synchronous step down DC/DC regulator capable of delivering up to 2A output current. It can 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.
