Автомобильное освещение - Противотуманные фары

Описание:
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.
Возможности:

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
