The IS32LT3960 is an asynchronous buck-boost LED driver controller with a built-in frequency dithering function and integrated PWM generator. It is designed to drive high-power LEDs in automotive applications, keeping constant LED current regardless of whether the supply voltage is above, below, or equal to the output voltage. It features a wide input voltage range from 4.5V to 60V and supports both analog and PWM dimming.
