Краткое описание:
42-V Dual Buck LED Controller with SPI Interface, Analog and PWM Dimming
Дополнительная информация
The TPS92518 is a dual-channel buck LED current controller featuring a SPI communications interface for multi-channel and platform lighting driver modules. It utilizes a quasi-hysteretic control method supporting switching frequencies from 1 kHz to 2 MHz, enabling high-frequency shunt FET dimming and handling dynamic loads of adaptive LED matrix systems. The device provides software-programmable set points for peak current, off-time, and output voltage sense.
