REFLED002 - Reference Design

Built-in Boost MOSFET, For Automotive Panel Backlight Applications, White LED Driver

The REFLED002 is a reference design of BD83A04EFV-M LED driver IC dedicated for automotive backlight application. It is including set of evaluation reports, design resources so that users can refer to board design as well as various test report provided in the design. BD83A04EFV-M is a white LED driver for LCD backlight. Built-in MOS for boost and 4ch constant current drivers for LED Drive, and it is suitable for high illumination LED drive. It is suitable for middle size LCD panel drive because LED pin maximum voltage is 50 V. The dimming is controlled by the PWM signal and can be set up to 20,000: 1@100 Hz. It also supports analog dimming and can accommodate even higher brightness ranges by combining with PWM dimming. The design require LED board attached to REFLED002-EVK-001 board.

  • Automotive backlight reference design
