ACT4525YH-T0001 Datasheet 40v/3.5a Cv/cc Buck Converter

Manufacturer: Qorvo

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

General Description

ACT4525 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.

ACT4525 has separated output current limits for dual port CLA applications.

With the separated current limits, the CLA can meet Apple’s MFi standard.

Key Features

  • Pass Apple MFi Test.
  • 40V Input Voltage Surge.
  • 4.5V-36V Operational Input Voltage.
  • Dual 5.1V Outputs with 1% Accuracy.
  • Up to 3.5A Output Current.
  • 2.65A Constant Current Regulation for VOUT1.
  • 1.2A Constant Current Regulation for VOUT2.
  • USB Auto-detect Support Apple 2.4A, Samsung and BC1.2 Devices.
  • Hiccup Mode Protection at Output Short.
  • 90% Efficiency at Full Load.
  • 0.5mA Low Standby Input Current.
