Datasheet 6ch White LED Driver Built-in Current Driver Buck-Boost and Boost DC/DC Converter for Automotive BD81A76EFV-M General Description 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. Key Specifications  Operating Input Voltage Range 4.5 V to 35 V  Output LED Current Accuracy ±3.
