50W Dual-stage LED Driver Reference Design with Adaptive Pre-boost Control for Automotive Headlights

Overview

TopologyBuck Converter
Input voltage18-45 V
Switching frequency50-2000 kHz
Output 124 V / 1 A
Output 224 V / 1 A
IC revisionB

Description

The TIDA-01520 dual-stage reference design drives two strings of LEDs for automotive headlight applications while automatically adapting the pre-boost voltage without the need of a microcontroller (MCU) which saves space and cost. Additionally, the design’s adaptive, pre-boost control reduces switching losses, maximizing system efficiency in automotive headlights.Notes: LM5122-Q1 is for pre-boost application on this evaluation board.

Features

  • Automatic adaption of pre-boost voltage to string length and temperature variations
  • Maximum LED string length per channel: 14 LEDs
  • CISPR 25 tested
  • Support of dynamic input voltage
  • Support of dynamic loads (Matrix/Dimming)

Typical applications

  • Exterior Headlight / Fog Light
