LMR51420 evaluation module 4.5-V to 36-V, 2-A synchronous step-down converter

Overview

TopologyBuck Converter
Input voltage4.5-36 V
Output 10.6 V / 2 A

Description

The UCC14240-Q1 evaluation module (EVM) is a DC/DC converter module, providing 1.5-W of 3 kVRMS, isolated power in a low-profile, 3.5-mm, wide body SOIC integrated package. The UCC12040EVM-052 EVM can operate from 21 V < VIN < 27 V and is configured for dual outputs of VDD = +15 V and VEE = -5 V, demonstrating typical bias supply voltages required by IGBT and SiC gate driver ICs used in high-voltage, industrial and automotive inverters, battery management systems, charging stations and various isolated equipment applications.

Features

  • 4.5-V to 36-V input voltage range
  • Default 5-V output
  • Up to 2-A output current
  • 500-kHz switching frequency
  • Hiccup mode short current protection
  • Internal compensation

Typical applications

  • appliances
  • General purpose wide VIN power supplies
  • Building automation, Motor drives
