AI
BD81A44MUV-M / BD81A44EFV-M (HTSSOP-B28 package) 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 (10,000:1 @100Hz dimming function) is possible by PWM input.
