Краткое описание:
High Voltage Current Mode PWM LED Lighting Controller
Дополнительная информация
The IS32LT3958A is a current mode PWM controller designed to drive a low side external NMOS FET for wide input/output voltage range and high LED current applications. It supports boost, buck-boost, SEPIC, and buck topologies. The device features a high-side sense resistor architecture for flexible current sensing and includes an integrated PWM generator for standalone dual brightness output. It is designed for automotive and high-performance lighting applications with extensive protection features including under-voltage lockout, over-voltage protection, and thermal shutdown.
