Datasheet LED Drivers for LCD Backlights 1ch Boost up type White LED Driver for large LCD BD9413F 1.1 General Description BD9413F is a high efficiency driver for white LEDs and is designed for large LCDs. BD9413F has a boost DCDC converter that employs an array of LEDs as the light source. BD9413F has some protect functions against fault conditions, such as over-voltage protection (OVP), over current limit protection of DCDC (OCP), LED OCP protection, and Over boost protection (FBMAX). Therefore it is available for the fail-safe design over a wide range output voltage. Key Specifications  Operating power supply voltage range: 9.0V to 35.0V  Oscillator frequency of DCDC: 150kHz (RT=100kΩ)  Operating Current: 3.3 mA(Typ.)  Operating temperature range: -40°C to +105°C 1.
