BD81A76EFV-M
6ch White LED Driver with Built-in Current Driver Buck-Boost DC/DC Controller for Automotive
BD81A76EFV-M is a white LED driver with the capability of withstanding high input voltage (maximum 35 V). This driver has 6ch constant-current drivers in 1-chip, where each channel can draw up to 120 mA (Max), and it is suitable for high illumination LED drive. Furthermore, a buck-boost current mode DC/DC converter is also built to achieve stable operation during power voltage fluctuation. Light modulation (10,000:1@100 Hz dimming function) is possible by PWM input.
