A8230A bias equivalent, ultra low-dropout constant-current without white led bias.
* Ultra Low 200mV Dropout at 20mA
* 0.6% High Accuracy Current Matching
* 20mA Full Scale Current
* 32 Level Linear Current Brightness Control
* PWM B.
For dimming control, an enable input pin is controlled by processor GPIO output pulses for 32 level linear current. Usi.
The A8230A is a high performance ultra lowdropout constant current bias supply for white LEDs. It can be used as an alternative to the simple ballast resistors in conventional parallel white LEDs applications. For dimming control, an enable input pin.
