General Description

BD8381AEFV-M is a white LED driver with the capability of withstanding high input voltage (50V MAX).

It has also an integrated current-mode, buck-boost DC/DC controller to achieve stable operation against high input voltage and to remove the constraint of the number of LEDs in series connection.

The LED brightness is controlled by either linear or PWM signal and is also possible to be controlled even without using a microcomputer, but instead, by means of the built-in PWM brightness signal generation circuit.
