Typical Application

Description
SY20623 is a 3MHz, 3A synchronous step-down converter which integrates an inductor and a control IC in one tiny package (3.0mm×3.0mm, H=1.0mm). It operates over a wide input voltage range from 2.75V to 5.5V. It integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Applications
· Mobile Phone, Smart Phone
· Bluetooth Headsets
· Wimax PDA, MID, UMPC
· Portable Game Console
· Digital Camera, Camcorder
