ACT4533C - Wide-Input Sensorless CC/CV Step-Down DC/DC Converter

Download the ACT4533C datasheet PDF. This datasheet also covers the ACT4533C-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

ACT4533C is a wide input voltage, high efficiency ActiveCC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

ACT4533C provides up to 3.5A output current at 125kHz switching frequency.

Key Features

  • 40V Input Voltage Surge.
  • 36V Steady State Operation.
  • Up to 3.5A output current.
  • Output Voltage up to 18V.
  • 125kHz Switching Frequency Eases EMI Design.
  • 91% Efficiency (Vout=5V@2.4A at Vin=12V).
  • Stable with Low-ESR Ceramic Capacitors to Allow Low-Profile Designs.
  • Integrated Over Voltage Protection.
  • Excellent EMI Performance.
  • Patented ActiveCC Sensorless Constant Current Control Improves Efficiency and Lowers.
