The IS32LT3960A/B is a peak current mode buck controller with an integrated PWM generator for high-brightness LED driving. It operates over a wide input voltage range of 5V to 60V and features internal high-side current sensing. The device supports two-step (dual brightness) PWM dimming and includes protection features such as over-temperature thermal roll-off, output short circuit, and over-voltage protection. It is designed for automotive applications including headlights, daytime running lights (DRL), and fog lights.
