ACT4533C - Step-Down DC/DC Converter

Datasheet Summary

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 3.5 A output current at 125 kHz switching frequency.

Features

  • 40 V Input Voltage Surge.
  • 36 V Steady State Operation.
  • Up to 3.5 A output current.
  • Output Voltage up to 18 V.
  • 125 kHz Switching Frequency Eases EMI Design.
  • 91% Efficiency (VOUT = 5 V@2.4 A at VIN = 12 V).
  • 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 Efficienc.
