Automotive Range Boost Converter Drives Two Strings of LEDs Reference Design

PMP8948

Design files

Overview

This wide input voltage range boost operates from an input of 9V - 32V and regulates current in two strings of 13 LEDs. Additionally, a second control loop monitors and regulates the input current during drop outs or faults. This low cost design operates at greater than 94% efficiency.
