7.5-W, 1.25-A, automotive buck LED driver reference design With analog and PWM dimming

This TI design showcases a TPS92515HV-Q1 small form factor LED driver optimized to drive two LEDs for a fog light design. The buck topology is implemented as a direct-to-battery, single-stage LED driver which results in a simple and cost-effective lighting solution. Additional design flexibility includes analog and PWM dimming support as well as cycle-by-cycle current limit and integrated thermal shutdown protection. EMI filtering has been included and designed to meet CISPR-25, Class 3 conduction requirements.

Features:

• Optimized for fog lights and other small form factor LED lighting applications
• CISPR-25 tested EMI
• Stays out of AM band
• Analog and PWM dimming
• Supports load dump up to 60V
