VOA300-DEFG-X017T中文资料威世科技数据手册PDF规格书

DESCRIPTION

The VOA300 linear optocoupler consists of an infrared

emitter irradiating an isolated feedback and an output PIN

photodiode in a bifurcated arrangement. The feedback

photodiode captures a percentage of the LEDs flux and

generates a control signal (IP1) that can be used to servo the

LED drive current. This technique compensates for the

LED’s non-linear, time, and temperature characteristics.
