Notes:

1. Do not exceed maximum current of 480mA.

Note: Do not exceed maximum current of 400mA in Preview Mode (continuous operation).

The AS3682 allows for the parallel connection of up to six current sinks to obtain the desired current range in Hard

Flash Mode (unused current sinks can be left open). For example, to obtain 280mA for Preview current, connect
