BD81A04EFV-M 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...
