ACT4523YH-T - CC/CV Step-Down DC/DC Converter

Download the ACT4523YH-T datasheet PDF. This datasheet also covers the ACT4523 variant, as both devices belong to the same cc/cv step-down dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

ACT4523 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.

ACT4523 provides up to 3A output current at 225kHz switching frequency.

Key Features

  • 40V Input Voltage Surge.
  • 38V Steady State Operation.
  • Up to 3A output current.
  • Output Voltage up to 12V.
  • Patent Pending Active CC Sensorless Constant Current Control  Integrated Current Control Improves Efficiency, Lowers Cost, and Reduces Component Count.
  • Resistor Programmable  Current Limit from 1.5A to 3A  Patented Cable Compensation from 0Ω to 0.3Ω.
  • ±7.5% CC Accuracy  Compensation of Input /Output Voltage Change  Temperature Compensation  Independent.
