REFLED003

Reference Design

A system-level evaluation board that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers.

REFLED003
6ch White LED driver BD82A26MUF-M reference design for
automotive panel backlight application (boost operation)

Summary

The REFLED003 is a reference design of BD82A26MUF-M LEDdriver 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.
BD82A26MUF-M is a white LED driver for LCD backlight. It has 6ch current drivers for LED drive, making it ideal for high brightness LED drive. LED pin maximum voltage is 50 V, making it suitable for driving large LCD panels.
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 REFLED003 board.

This reference design consists of two boards. Each is shown in the table below.
