SY8113D - Synchronous Step Down Regulator

Description

The SY8113D is a high efficiency 500kHz synchronous step-down DC/DC converter capable of delivering 3A current.

The SY8113D operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

  • Low RDS(ON) for Internal Switches (Top/Bottom): 80mΩ/40mΩ.
  • 4.5-18V Input Voltage Range.
  • 3A Output Current Capability.
  • 500 kHz Switching Frequency.
  • Instant PWM Architecture to Achieve Fast Transient Responses.
  • Cycle-by-cycle Current Limitation.
  • Hiccup Mode Short Circuit Protection.
  • Power Good Indicator.
  • Programmable Soft-start Time to Limit the Inrush Current.
  • ±1.5% 0.6V Reference.
  • Thermal Shut Down With Auto-recovery.
  • RoHS Compliant an.

SY8113D High Efficiency, 500kHz, 3A, 18V Input Synchronous Step Down Regulator General Description The SY8113D is a high efficiency 500kHz synchronous step-down DC/DC converter capable of delivering 3A current. The SY8113D operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 500kHz switching frequency.
