ACT4501 - 1.25A CC/CV Step-Down DC/DC Converter

Download the ACT4501 datasheet PDF. This datasheet also covers the ACT4501-Active variant, as both devices belong to the same 1.25a cc/cv step-down dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

ACT4501 is a dedicated cost-effective DC-DC converter for 5V/1A car charger applications with a wide input voltage and high efficiency.

The converter operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

Key Features

  • 10V-30V Input Voltage.
  • 40V Transparent Input Voltage Surge.
  • Up to 1.25A Constant Output Current.
  • Output Voltage up to 12V.
  • Good EMC Performance on Single Layer PCB.
  • Patent Pending ActiveCC Constant Current Control.
  • Integrated Current Control Improves Efficiency, Lowers Cost, and Reduces Component Count.
  • Resistor Programmable Outputs.
  • Current Limit from 500mA to 1250mA Patented cable compensation from DC Cable Compe.
