for Automotive Light  
BD8381EFV-M  
No.11039EAT14  
Description  
BD8381EFV-M is a white LED driver with the capability of withstanding high input voltage (50V MAX).  
A current-mode buck-boost DC/DC controller is also integrated to achieve stable operation against 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 DC. The PWM brightness signal generation circuit is built into, and the  
control without microcomputer is also possible.  
Features  
1) Input voltage range 5.0 – 30 V  
2) Integrated buck-boost current-mode DC/DC controller  
3) Built-in CR timer for PWM brightness  
4) PWM linear brightness  
5) Built-in protection functions (UVLO, OVP, TSD, OCP, SCP)  
6) LED error status detection function (OPEN/ SHORT)  
7) HTSSOP-B28 package  
Applications  
Headlight and running (DRL) of night of daylight, etc.
