TOP243Y / TOP244Y 'Topswitch' SMPS regulator IC needed

Jan 01, 2007 3 Replies

Hi all and a very Happy New Year ;)



This is my first post & look forward to learning & helping when I can.



I need a TOP243Y or TOP244Y switch regulator IC for a Switch Mode Power Supply.



It's similar in appearance to a stand TO220 transitor, but it has 6 legs.



The only place I can seem to get one is digikey USA, but shipping to the UK is a flat =A335 ;-(



If any one can help, I'd be really grateful.



Many thanks - Richard (UK) - Skype ' timetec '



I get 'em from Mouser. BTW, its not a regulator, its the oscillator/driver for the transformer.

If you can persuade Power Integrations you're a serious designer they'll send you free samples.

Farnell stocks them too.
