SY8843

Overview

The SY8843 and SY8843L are high efficiency 1.5MHz synchronous step down DC/DC regulators capable of delivering up to 3A output current. The SY8843 and SY8843L can operate over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

  • 2.7~5.5V Input Voltage Range
  • 65µA Low Quiescent Current
  • Ultra Fast Load Transient Speed
  • Low RDS(ON) for Internal Switches (Top/Bottom) 85mΩ /50mΩ
  • High Switching Frequency 1.5MHz Minimizes the External Components
  • Internal Soft-start Limits the Inrush Current
  • Reliable Short Circuit Protection  SY8843: Hic-cup Mode Protection  SY8843L: Latch Off Protection
  • Reliable OVP and OTP Protection  SY8843: No Latch Off Protection  SY8843L: Latch Off Protection
  • Output Auto Discharge Function
  • RoHS Compliant and Halogen Free
