6ch boost LED driver which constant setting can be shared by I2C control - BD9423EFV
BD9423EFV is a high efficiency driver for white LEDs and designed for large LCD panel. This IC is built-in high current drive and high responsibility type 6ch LED drivers and 1ch boost DCDC converter. BD9423EFV has some protect function against fault conditions, such as the over-voltage protection (OVP), LED OPEN and SHORT protection, the over current limit protection of DCDC (OCP). Therefore BD9423EFV is available for the fail-safe design over a wide range output voltage. Moreover the functions and the detection voltage can be controlled by the I2C. This enables for the constant setting of external parts to be shared by I2C control, nevertheless the different usage condition.
