     SY20019E is a high efficiency 1.5MHz synchronous step down DC/DC regulator, capable of delivering up to 1A 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.

    SY20019E is in a space saving, low profile SOT563 package.
