IS32LT3964-GRLA3-TR
Dual Channel Synchronous Buck LED Driver with PWM/Analog Dimming
The IS32LT3964 is a dual-channel, high-frequency, synchronous step-down LED driver featuring integrated power MOSFETs. It is designed to provide highly accurate constant current for driving high-power LEDs. Each channel supports independent PWM and analog dimming, providing flexibility for automotive and industrial lighting applications. The device includes spread spectrum technology for improved EMI performance and comprehensive protection features including over-temperature, output short-circuit, and cycle-by-cycle current limiting.
