BD9479FV is a high-efficiency white LED driver specifically designed for large LCD panels, utilizing a boost DC-DC converter to power an array of LEDs. It features an 8-channel constant current driver with a maximum LED setting current of 500mA, allowing for precise control over brightness. The device supports both analog and individual channel PWM dimming functions, enhancing flexibility in lighting applications. Built-in protection mechanisms include over-voltage protection (OVP), over-current limit protection (OCP), short circuit protection (SCP), and open detection for LED strings, ensuring reliable operation under fault conditions. The operating voltage range is from 9.0V to 35.0V, with an oscillator frequency of 150kHz. The device operates within a temperature range of -40¬8C to +85¬8C, making it suitable for various environmental conditions. The BD9479FV is packaged in an SSOP-B40 format, measuring 13.6mm x 7.80mm x 1.80mm, with a pin pitch of 0.65mm. This product is ideal for applications in TVs, computer displays, and notebook LCD backlighting.
