Another important concern is the balance of currents that flow in multiple strings. We know that two or three strings of LEDs will have different combined forward voltages. The LED driver will deliver ...
Supertex’s HV9925, a LED driver IC with adjustable output current and pulse width modulated (PWM) dimming, is optimized for driving multiple-LED strings in offline applications such as decorative ...
In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...
