ACT4533 - Wide-Input Sensorless CC/CV Step-Down DC/DC Converter

Download the ACT4533 datasheet PDF. This datasheet also covers the ACT4533-Active variant, as both devices belong to the same wide-input sensorless cc/cv step-down dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

ACT4533 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

ACT4533 provides up to 3A output current at 125kHz switching frequency.

Key Features

  • 40V Input Voltage Surge.
  • 32V Steady State Operation.
  • Up to 3A Output Current.
  • Constant Current Output with Input up to 32V.
  • Output Voltage up to 12V.
  • 125kHz Switching Frequency Eases EMI Design.
  • Good EMI Performance to Pass EN55022 Radiation Regulation without adding EMI Components.
  • Patent Pending Active CC Sensorless Constant Current Control.
  • Integrated Current Control Improves Efficiency, Lowers Cost, and Reduces.
