An LED driver IC for automotive applications must meet many requirements. It must be flexible, implementing multiple functions like high beam, low beam, fog lights, daytime running lights (DRLs), ...
The second dimming input possibility of the RCD series is the PWM input. Pulse width modulation uses a digital control signal to alter the brightness of the LED by switching it on and off too rapidly ...
The GLCD 30 series of universal-input, constant-current 30-W LED drivers offers three-way dimming: 0 to 10 V dc, pulse-width modulation, and 10- to 100-kΩ resistance external dimming control. The GLCD ...
