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.
