Overview

The SY80004 is a high efficiency 2.2MHz synchronous step down DC/DC regulator capable of delivering up to 4A output current. It can operate over a wide input voltage range from 2.5V to 5.5V and integrates main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.

  • 2.5V to 5.5V Input Voltage Range
  • Ultra-Fast Load Transient Speed
  • Low RDS(ON) for Internal Switches (Top/Bottom): 38mΩ /30mΩ
  • High Switching Frequency 2.2MHz Minimizes the External Components
  • ±1% Feedback or Output Voltage Accuracy (Full Temperature Range)
  • PFM Mode for Light Load Efficiency
  • 21μA Operating Quiescent Current
  • Internal Soft-start Limits the Inrush Current
  • 100% Dropout Operation
  • Output Auto Discharge Function
