New 4 Channel Highside driver

[steve-o]

Funny how China isn't trying to flood us with their analog driver boards .. they have 'em in all of their DI diode modules .. it's strange ..
--@ Steve -- I hope your friends continue with their "cottage" project, and/or Buffo/Keck's project gets off the ground. I guess the Pango driver is going to take a while for product development . I wonder why TI/ National etc doesn't have a chip yet .. I guess not enough demand / niche market ..

Seems there are a few drivers that will appear soon.

Heres my offering, small 1" x 2" driver. Prototypes all done and tested OK. Just in the middle of getting a assembly run done...

You must work together guys ! you must build a dual driver AND a tec driver, off course in the same board !

If there is enough interest, we ca make it. To put a dual or even 4 channel driver with a tec driver on the same board isnt a big deal.

Let me check the temp in hell... still hot. So NOBODY

not because of some guys here who would make them for their own use but because of many bad guys watching PL who will make money with
with other people work.

It's all here and very old already: http://www.photonlexicon.com/forums/...and-TEC-Driver
Shouldn't be a big deal to adapt this to the current needs. In fact a successor of this old one was made for a groupbuy at LF some years ago and is field proven (over 200 units made in the groupbuy at this time): http://www.laserfreak.net/forum/view...49839&start=75
Any other highside driver uses the same principle circuit anyways, including the badpip driver and many others. The use of the old schematic and layout is free to use for personal use, so get your soldering iron out!

Something in the works, Dave? Very interesting .. looking forward to the results of the HALT testing (j/k) .. When are they going to be around and about? Any time-frame estimation ? Were they designed by engineers or hobbyists?

Yep, another high side driver very loosely based on Andy's design, but with beam supression, startup delay.. Production takes about a month from when I order, which should be soon at this rate.. I just want to run over some more tests before pulling the trigger on a run of 100 assembled boards..
