This reference design showcases a small form factor LED driver (TPS92515HV-Q1) 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 is simple and cost-effective lighting. 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.
