Overview

This reference design showcases the TPS92682 and the TPS92520 as a fully self functional three-channel LED driver for headlight applications.  The design is intended to be a low-cost halogen headlight module replacement compatible with an automotive body control module.  The three LED channels drive highbeam/lowbeam, turn indicator and daytime running light, and position marker light.  The design uses one TPS92682 dual channel controller as a constant voltage boost and a constant current SEPIC.  It also uses one TPS92520 supplied by the boost for two synchronous rectified constant current buck converters. The board is designed with ground strip to allow enclosing the power stages for EMI compliance which includes CISPR 25 Class 5 conducted test results.

Features
  • Two stage constant voltage boost converter supplying two synchronous buck converters for highbeam/lowbeam and turn indicator
  • Supplying two synchronous buck converters for
  • Highbeam/lowbeam and turn indicator
  • SEPIC converter for day time running light and position marker light
  • Compatible with power supplied from body control module
  • Highbeam/lowbeam and turn indicator single LED short, output short and open string detection for fault reporting and disabling
  • Reverse battery protection
