Краткое описание:
Low Dropout, Two-Bank LED Driver with PWM Brightness Control
Дополнительная информация
The TPS75105 is a linear low dropout (LDO) matching LED current source optimized for low-power keypad and navigation pad LED backlighting. It provides constant current to up to four unmatched LEDs organized in two banks of two LEDs each in a common-cathode topology. The device features a default factory-programmable preset current level and can be used without external components, though an optional external resistor allows for high-accuracy user-programmable current.
