The IS32LT3967B is a dual-channel switching LED driver controller featuring a wide input voltage range and support for multiple topologies including buck, boost, buck-boost, and SEPIC. It is designed for automotive applications such as high beam/low beam headlights and daytime running lights. Each channel can be independently controlled with PWM for dimming and includes protection against over-voltage, output short-circuits, and thermal overload. It incorporates spread spectrum technology and frequency synchronization to minimize EMI signatures.
