Fluorescent Display Tube Controller Driver

Princeton Technology 

APPLICATION CIRCUIT

PT6321

Notes:

*1. The VDISP voltage depends on the fluorescent display tube used. Adjust the value of the constants R3 and ZD to the VDISP voltage used.

*2. The value of R1 & C1 depend on PT6321 supply voltage of VDD (VDD=5V: R1=3.3KΩ, C1=47pF; VDD=3.3V: R1=3.3KΩ, C1=39pF)

*3. R2=1KΩ, C2=0.1µF
