ACP2766 Overview
The ACP2766 is a step-up DC-DC converter which operating as current source to drive white LEDs. The light intensity of LEDs is proportional to the current passing through them. The default white LEDs current is set with the external resistor, and the feedback voltage reference is set to 200mV.
