Overview

Datasheet 4-Channel Back-Boost White LED Driver with Integrated FET for up to 32 LEDs BD81A04EFV-M ●General Description BD81A04EFV-M is a white LED driver with the capability of withstanding high input voltage (40V MAX).
This driver has 4ch constant-current drivers integrated in 1-chip, which each channel can draw up to 120mA 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 PWM techniques.
The set board can be made a conserve ...
