A8230A - ULTRA LOW-DROPOUT CONSTANT-CURRENT WITHOUT WHITE LED BIAS

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 is controlled by processor GPIO output pulses for
