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