General Description

The SY8883 is a high efficiency 1MHz synchronous step down DC/DC regulator, which is capable of delivering up to 3A output current.

It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

The SY8883 integrates reliable latch off function when output over voltage, output short or thermal shutdown happens.

Key Features

  • 2.5V to 5.5V Input Voltage Range.
  • 55μA Low Quiescent Current.
  • Low RDS(ON) for Internal Switches (Top/Bottom): 85mΩ /60mΩ.
  • High Switching Frequency 1MHz Minimizes the External Components.
  • Internal Soft-start Limits the Inrush Current.
  • 100% Dropout Operation.
  • Power Good Indicator.
  • Reliable Latch off Function When:.
  • Output Under Voltage.
  • Thermal Shutdown.
  • Output Voltage>120% of Regulated Voltage.
  • Output Auto Discharge Function.
  • RoHS.
