You see I am a chinese,and I had a lot of NOT FAKE LM9022 made by NS
all brand new in org pack,and as me experiance in driving VFD stuffs
,I only used this chip in one project,and I think this chip is too old
for the current tech,by using only two mosfets and drived via a MCU
tim can replace this
I found this module via Ebay last week,and got one yeaterday,for
lighting up 6 IN-18 tubes at the same time,the module chip,the
mosfet,the transform get almost no heat,unbelieveable.
Efficiency:92.3%;
