BD82A26MUF-M
Nano Cap™, White LED Driver for Automotive with 6ch Current Driver Integrated, Built-in Boost DC/DC Converter
This IC 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 50V, making it suitable for driving large LCD panels.
What is Nano Cap™?
Nano Cap™ is a combination of technologies which allow stable operation even if output capacitance is connected with the range of nF unit.

Supporting Information
Overview
These products leverage proprietary low power consumption technology to reduce losses in LED driver current control circuits. The result is 20% lower overall IC power consumption compared to conventional products under typical conditions (80mA/ch LED circuit current, 12V power supply). This contributes to lower power consumption in medium- to large-sized automotive displays where power consumption is an issue.
At the same time, all models are equipped with both DC and PWM dimming to meet a wide range of requirements. As there no longer exists a need to switch current feedback mode for low/high brightness change with ROHM’s original seamless PWM dimming technology, flickering that occurs with general PWM dimming is reduced, improving system reliability.
Application Examples
• Instrument clusters
• Car infotainment
• Head-up displays (HUDs)
• Electronic mirrors (side/rear view)
Compatible with a wide range of display sizes from 5-inch to 10+ inch class.
