500kHz 16V 2A Synchronous DC/DC Buck Converter

Overview

TopologyBuck Converter
Input voltage4.5-16 V
Output 11.2 V / 2 A
IC revision1

Description

The AP65251 is an adaptive constant on-time mode synchronous buck converter providing high efficiency, excellent transient response and high DC output accuracy for low-voltage regulation in digital TVs, set-top-boxes, and network systems. The constant-on-time control scheme handles wide input/output voltage ratios and provides low external component count. The internal proprietary circuit enables the device to adopt ultra-low ESR ceramic capacitors.

Features

  • VIN 4.5V to 16V
  • 2A Continuous Output Current, 2.5A Valley
  • Efficiency Up to 95%
  • Automated Light Load improvement
  • VOUT Adjustable to 0.6 to 6V
  • 500kHz Switching Frequency
  • Internal Soft-Start
  • Enable Pin
  • Over current Protection (OCP) with Hiccup
  • Thermal Protection
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)

Typical applications

  • Gaming Consoles / Flat Screen TV sets and Monitors / Set Top Boxes / Home Audio / Consumer electronics
  • Network Systems
  • Distributed power systems / FPGA, DSP and ASIC Supplies
