SY8088AAC

General Description

SY8088 is a high efficiency 1.5Hz synchronous stepdown DC DC regulator IC capable of delivering up tolA output current. It can operate over a wide inputtoltage range from 2.5 to 5.5W and integrate mainswitch and synchronous switch with very low RDS(ONto minimize the conduction loss.
