simple non-isolated 30w CC PS

Posted by: sysWOW64 on

Dear engineers,  i am interested to use your LinkSwitch in our new LED power supply.  unfortunatly I failed to find suitable demo board for required parameters or parameter are not mentioned. Please, advise demo board schema for the followwing:

Input: AC 170-265, Output: 90-100V 300-350 mA Constant Current. PF > 0.95,  current ripple < 5%.

Driver should be simple and cheap, thats why non-isolated. 

PS. Isolated solution we already have, but new ideas are welcome.

Requirement is 300mA(better 350), 30w this example is only 150 :(
