Краткое описание:
65-V dual buck LED controller with SPI interface, analog and PWM dimming
Дополнительная информация
The TPS92518HV is a dual-channel buck LED current controller featuring a SPI communications interface. It utilizes a quasi-hysteretic control method supporting switching frequencies from 1 kHz to 2 MHz, designed to handle dynamic loads of adaptive LED matrix headlamp systems. The device features software-programmable set points for precision peak current, controlled off-time, and output voltage sense, allowing for a single driver solution to support multiple load configurations.
