DC/DC Converter, 4.5 V to 18 V, 30 A

Overview

TopologyBuck Converter
Input voltage4.5-18 V
Output 10.6 V / 30 A

Description

The NCP3230 is a high current, high efficiency, voltage−feed−forward voltage−mode synchronous buck converter which operates from 4.5 V to 18 V input and generates output voltages down to 0.6 V at up to 30 A load.

Features

  • Wide Input Voltage Range from 4.5 V to 18 V
  • 0.6 V Internal Reference Voltage
  • 500 kHz Switching Frequency
  • External Programmable Soft−start
  • Lossless Low−side FET Current Sensing
  • Output Over−voltage Protection and Under−voltage Protection
  • System Over−temperature Protection using a Thermistor or Sensor
  • Hiccup Mode Operation for All Faults
  • Pre−bias Start−up
  • Adjustable Output Voltage
  • Power Good Output
  • Internal Over−temperature Protection
  • This is a Pb−Free Device

Typical applications

  • High current POL applications, powering asics, fpga, and DSPs
