ACT4527 - CV/CC Buck Converter

Download the ACT4527 datasheet PDF. This datasheet also covers the ACT4527-Active variant, as both devices belong to the same cv/cc buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

ACT4527 is a wide input voltage, high efficiency step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

ACT4527 has an interface for USB-PD control via a tri-state digital pin.

Key Features

  • USB-PD Support.
  • 40V Input Voltage Surge.
  • 4.5V-36V Operational Input Voltage.
  • 5.1V/9.1V/12.1V Output with +/-1% Accuracy.
  • Up to 3.0A Output current.
  • Constant Current Regulation Limit.
  • Hiccup Mode Protection at Output Short.
  • >90% Efficiency at Full Load.
  • 0.5mA Low Standby Input Current.
  • 5.7V/10.1V/13.5V Output Over-voltage Protection for 5.1V/9.1V/12.1V Outputs.
  • Cord Voltage Compensation.
  • Meet EN55022 Class B Radiated EMI Standard.
