Description

General part information

BD9470AFM Series

BD9470AFM is high efficiency driver for white LED. They are designed for large sized LCD. BD9470AFM is built-in DCDC converter that supply appropriate voltage for light source. BD9470AFM is also built-in protection function for abnormal state such as OVP: over voltage protection, OCP: over current limit protection of DCDC, SCP: short circuit protection, open detection of LED string. Thus they are used for conditions of large output voltage and load conditions.
