Output:
The current: 320mA Constant current
The voltage between 30~70 Volt DC
Input:
180~240 volt Ac
can any one help me to find right IC for make driver? is there any software or demo board for easier design?

Dear Friends,
I checked PI site and check some models datasheet.
I think i must choose ic by flyback or buck topology.
But i need 30~70 volt output and all IC output is under 70.
How can increase voltage in circuit? can you inform me some article about constant current power design? I need advise for find my way in design.
Best Regards,
Arad

Thanks PI-Surak
I checked the table for choose IC, I think the price of tiny switch 3 is cheaper, can i use that for ip 67 driver? (Not open frame)
Can i buy any demo board for 10~18W?
Thanks a lot

Dear Sir,
How i can use LINKSWITCH-PH in PI expert design software.
Because it has only linkswitch cv and xt.
I`m wait for your reply,
