FS: SKDRIVER for 7w, KDRIVER buck 2.6A, boost 1.1A, linear 0.8A

I thought I had been straight forward on this issue. I don't want to take sides on anything either. I received three drivers for testing. A linear, boost and buck and, unfortunately, none of them would regulate current at all. It didn't seem as though they were setup to do that. I was hoping that they would work well and would be a source of new drivers for us all. But, they were not.
 





HMMMM...Sounds like we have..." A Failure to Communicate ".....Quote: "Cool Hand Luke"
No ...Paul...you were crystal clear....You tested....they failed.....It seemed as though.....Thanh....er….missed your review....somehow ?????

Anyway....I would assume he will send you three (3) of the next generation....and....hopefully....they will do good !!! Keep us posted !!!

Bump... BTW, Im glad you guys gave encouragement vs ripping him a new one. Language /cultural barrier I suppose in responding to Pauls results.

This place was rough back in the day. You would figure laser nerds are a decent bunch(which the guys here now are) but some real a holes circa 2008 2009.
 
update my product option KdriverV3 buck : current adjustable 0.4 - 6A+
- square size : 13x18mm(0.51x0.7 inches)
- with # round size : 22mm (the hole at center to the way which the wire go through it for connecting to source or diode)
- Over heat protection, all data like same as SKdriverV2

So sad these failed testing. I would have loved to buy a few.

his last post was mid Jan 2019..I hoped to see new tests..
left hanging' here.

If Than wants somebody else to test these I see no problem..
Paul will not take that personally....--as was said- 'we need new drivers' ATM.

Working on that, I have received the components for my now fixed current up to 3A buck, I changed the design for fixed because it allows me to get a much smaller footprint, I have still kept the reverse polarity protection mosfet and it's complimentary components, optimized the efficiency (around the 92.6% mark with 8.4v in 3A 4.7v out), the final footprint is designed to be less than 10mm x 14mm and I will be including low resistors with every driver so the customer can change the current setting if he changes his mind. They also have a pwm in pad. When I return from holidays I'll design a much needed boost driver too.
