Current Settings

CYT3000A is LED constant current drive control circuit, integrated multi-functions module such as LED constant current control module, the OUT port driver module and so on. The IC CYT3000A D1 port minimum input voltage is 6 v (IOUT = 20 ma), can be achieved through external REXT resistance output current from 10mA60mA, built-in LED constant current driver module can make the LED current in high precision and is not affected by environmental temperature.IC CYT3000A can be realized through step by step to open four switch high efficiency, high power factor.
  CYT3000A output current adjusted by REXT resistance, IOUT = VREXT/R, 4 level switch opens output current step by step as follows:
 ID1=0.55V/R       ID2=0.70V/R       ID3=0.85V/R       ID4=0.90V/R
