General Description
The AP8801 is a step-down DC/DC converter designed to drive LEDs with a constant current.
The device can drive up to thirteen LEDs, depending on the forward
voltage of the LEDs, in series from a
voltage source of 8V to 48V.
Series connection of the LEDs provides identical LED cu...
