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.
