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.
