4ch White LED Driver with Buck-Boost (40 LED Maximum) - BD81A24EFV-M

BD81A24EFV-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 (5000: 1 dimming function) is possible by PWM input.
