Datasheet LED Drivers for LCD Backlights 1ch Boost up type White LED Driver for large LCD BD9486F 1.1 General
BD9486F is a high efficiency driver for white LEDs and is designed for large LCDs. BD9486F has a boost DCDC converter that employs an array of LEDs as the light source. BD9486F 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 18.0V Oscillator frequency of DCDC: 150kHz (RT=100kΩ) Operating Current: 2.6mA(Typ.) Operating temperature range: -40°C to +85°C W(Typ) x D(Typ) x H(Max) 10.00mm x 6.20mm x 1.71mm Pin pitch 1.27mm 1.2 Package(s) SOP16 Features DCDC converter with current mode VOUT discharge function at shutdown LED protection circuit (Over [ … ]
