Application Circuits of NCP5602 and NCP5612

Published:2011/6/14 12:57:00 Author:Michel | Keyword: Application Circuits

Gradual brightness changes is mainly applied to create the theatre type illuminating effect when portable electronic devices get started or closed.At startup when backlit current will be gradually amplified to 20mA in a predetermined time interval in stepping way and it will be gradually reduced when it gets colsed.Microprocessor sends different frequencies PWM signals to LED drivers' end and the LED current is increased or reduced through many stepping ways in a time interval,which achives the effects.This method shortcoming is that it consumes real-time processor,for example,this happens on NCP5602 and NCP5612's LED driver chips.   (View)
