4-Channel Buck-Boost White LED Driver for up to 40 LEDs - BD8119FM-M

BD8119FM-M is a white LED driver with the capability of withstanding high input voltage (36V Max.). This driver has 4-ch constant-current drivers integrated in 1-chip, which each channel can draw up to 150mA max, so that high brightness LED driving can be realized. Furthermore, a current-mode buck-boost DC/DC controller is also integrated to achieve stable operation against unstable car-battery voltage input and also to remove the constraint of the number of LEDs in series connection.The brightness can be controlled by either PWM or Linear techniques.
