98% Efficient 30W Synchronous Automotive Pre-Boost Reference Design

Overview

TopologyBoost Converter
Input voltage6-16 V
Output 112 V / 2.5 A
IC revisionA

Description

98% Efficient 30W Synchronous Automotive Pre-Boost Reference Design. PMP11479 is a synchronous boost power supply using the LM5122-Q1 controllers. The design accepts an input voltage of 6Vin to 16Vin, and boosts a 12Vout rail capable of sourcing 2.5A continuous current. The LM5122-Q1 has an internal current source to keep the high side FET to run at 100% duty cycle which allows a bypass operation when the input voltage is greater than the configured output voltage.

Features

  • 6V to 16V in, output 12V@ 2.5A
  • Achieving efficiency of 98% at 12Vin
  • High density design
  • Solution size: 36mm x 23mm
  • Overvoltage and overcurrent protection
