Typical Application

Description

The SY20623A 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=1.1mm max). 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
