White LED Driver for large LCD Panels - BD9428
BD9428 is a high efficiency driver for white LEDs and designed for large LCDs. This IC is built-in a boost DCDC converters that employ an array of LEDs as the light source. BD9428 has some protect function against fault conditions, such as the over-voltage protection (OVP), the over current limitprotection of DCDC (OCP), the short circuit protection (SCP), the open detection of LED string. Therefore BD9428 is available for the fail-safe design over a wide range output voltage.
