Typical Application

Description

SY20622 is a 3MHz, 2A 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.

·           Mobile Phone, Smart Phone

·           Bluetooth Headsets

·           Wimax PDA, MID, UMPC

·           Portable Game Console

·           Digital Camera, Camcorder
