Datasheet 4ch White LED Driver Built-in Current Driver Buck-Boost and Boost DC/DC Converter for Automotive BD81A44EFV-M BD81A44MUV-M General Description Key Specifications BD81A44EFV-M / BD81A44MUV-M is a white LED driver with the capability of withstanding high input voltage (maximum 35 V). This driver has 4ch constantcurrent 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. Features ◼ Operating Input Voltage Range 4.5 V to 35 V ◼ Output LED Current Accuracy ±3.
