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.
