White LED Driver for large LCD Panels (DCDC Converter type) - BD93942F
BD93942F is a high efficiency driver for white LEDs and designed for large LCDs. These ICs are built-in a boost DCDC converters that employ an array of LEDs as the light source. BD93942F have some protect function against fault conditions, such as the over-voltage protection (OVP), the over current limit protection of DCDC (OCP), the short circuit protection (SCP), the open detection of LED string. Therefore BD93942F are available for the fail-safe design over a wide range output voltage.
