4-Channel Back-Boost  
White LED Driver  
with Integrated FET for up to 32 LEDs  
BD81A04EFV-M  
General Description  
Key Specifications  
BD81A04EFV-M is a white LED driver with the capability  
of withstanding high input voltage  
Power supply voltage  
LED output current accuracy  
Oscillation frequency  
Operating temperature range  
PWM minimum pulse width  
LED maximum output current  
4.5 to 35 [V]  
±3.0 % @50mA  
200 to 2200 KHz  
-40 to 85 ℃  
(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 area  
because MOSFET is built into  
1usec
