General Description
BD81A74EFV-M / BD81A74MUV-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.
