Texas Instruments TPS92515HV-Q1 | Demoboard TIDA-01520
50W Dual-stage LED Driver Reference Design with Adaptive Pre-boost Control for Automotive Headlights
Overview
| Topology | Buck Converter |
| Input voltage | 18-45 V |
| Switching frequency | 50-2000 kHz |
| Output 1 | 24 V / 1 A |
| Output 2 | 24 V / 1 A |
| IC revision | B |
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
