The IS32LT3962 is a dual-channel DC-to-DC switching converter that integrates two N-channel MOSFETs to operate in a buck configuration. It supports an input voltage range from 4.5V to 38V and provides a constant current of up to 1.5A per channel for driving multiple series-connected LEDs. The device features spread spectrum for optimized EMI performance and logic-level PWM dimming for independent brightness control of each channel. It includes robust fault protection for LED open/short circuits and thermal shutdown.
