TOP234Y / TOP244Y 'Topswitch' SMPS Switching Regulator needed

Jan 01, 2007 1 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 switching 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 '



www.farnell,co.uk says TOPS243Y no longer stocked, but TOPS244 YN *is* in stock at £1:82. See

Postage, etc- I dunno, but at least it's in UK.
