General Description

The SY8002A1 is a high efficiency 1.5MHz

synchronous step down DC/DC regulator, which is

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.

The low output voltage ripple, the small external

inductor and the capacitor sizes are achieved with

1.5MHz switching frequency.
