Onsemi NCP3235 | Demoboard ONSEC-18-017

4.5 V to 23 V, DC/DC Converter with Integrated MOSFETs

Overview

TopologyBuck Converter
Input voltage4-21 V
Output 10.6 V / 15 A
IC revision1.0

Description

The NCP3235 is a 15 A DC/DC converter with internal MOSFETs and offers flexibility in design. The device can deliver an adjustable output voltage as low as 0.6V to over 80% of the input voltage. Features include adjustable current limit, output voltage, and soft-start timing. Pin selectable features enable switching frequencies of 550 kHz or 1 MHz, selecting DCM/CCM operating modes, and the ability latch off or hiccup mode during over current. The part can be configure to operate in ultra-sonic mode to stay out of the audio band. The part is offered in a thermally enhanced 6mm by 6mm TQFN package.

Features

  • Accurate 0.6 V reference
  • DCM/CCM selectable options
  • 550kHz/1.1MHz switching frequency
  • Ultra-sonic mode
  • Thermally enhanced QFN package
  • Wide operating range 4.5 V to 21 V
  • Adjustable soft start

Typical applications

  • Computing/Servers
  • Datacom/Networking
  • FGPA, ASIC, DSP power / 12 V Point of load
