ACT4527 Datasheet Cv/cc Buck Converter

Manufacturer: Active-Semi

Overview: ACT4527 Rev 1, December 28th, 2015 40V/3.0A CV/CC Buck Converter Featuring.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Vout is 5.1V if this pin is floating, Vout is 9.1V when this pin voltage is less than 0.8V and Vout is 12.1V while this pin voltage is more than 2.0V.

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.
