Краткое описание:
Low Dropout, Two-Bank LED Driver With PWM Brightness Control
Дополнительная информация
The TPS7510x linear low dropout (LDO) matching LED current source is optimized for low-power keypad and navigation pad LED backlighting applications. The device provides a constant current to up to four unmatched LEDs organized in two banks of two LEDs each in a common-cathode topology. It features 2% LED-to-LED matching and can provide up to 25 mA per LED. Brightness control is achieved using PWM signals on the enable pins, and the device operates without internal switching signals to eliminate EMI.
