Beschreibung

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.

Eigenschaften

  • 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)

Typische Anwendungen

  • Exterior Headlight / Fog Light
