General Description

The SY8892 is a high efficiency 1.5MHz

synchronous step down DC/DC regulator, capable of

delivering up to 2A output currents. It can operate

over a wide input voltage range from 2.5V to 5.5V

and integrates main switch and synchronous switch

with very low RDS (ON) to minimize the conduction

loss.

The SY8892 is in a space saving, low profile

SOT563 package.
