BD81A34MUV-M/EFV-M is a white LED driver with the capability of withstanding high input voltage （35V Max）。 This driver has 4ch constant-current drivers integrated in 1-chip， where each channel can draw up to 120mA （Max）， which is also suitable for high illumination LED drive. Furthermore， a buck-boost current mode DC/DC controller is also integrated to achieve stable operation during power voltage fluctuation. Light modulation （dimming function） is possible by PWM input.
