Advanced Dimming Capable Buck LED Driver Reference Design for Industrial IR LED Applications(PMP15022)
This TI Design showcases a TPS92515 small-form factor LED driver optimized to drive up to 5 infrared (IR) LEDs for industrial cameras and other general lighting designs. It can drive up to 1A through LED loads of up to 9.5V from a 24V input source. The buck topology is implemented as a secondary-stage LED driver which offers a simple, high performance and a cost effective lighting solution. Additional design flexibility includes analog and PWM dimming (including shunt FET dimming) support as well as EMI filtering designed to meet FCC part 15 class B conduction requirements.
Optimized for infrared LEDs and other small form factor LED lighting applications FCC part 15 class B tested EMI Small inductor size (4mm X 4mm) Analog and PWM dimming Supports high frequency shunt FET dimming up to 30 kHz
