LED Driver for LCD Backlights  
White LED Driver for 4Ch Large LCD Panels  
(DC/DC converter type)  
BD9415FS  
1.1 General Description  
BD9415FS is a high efficiency driver for white LEDs and  
designed for large LCDs. This IC has a built-in boost  
DC/DC converter that employs an array of LEDs as the  
light source. BD9415FS has various protection functions  
against fault conditions, such as over-voltage protection  
(OVP), over current limit protection of DC/DC (OCP),  
short circuit protection (SCP), over duty protection  
(ODP) and open detection of LED string. Therefore,  
BD9415FS is available for the fail-safe design over a  
wide range of output voltages.
