LT4320 based active rectifier

[gary s]

Hi Prasi,

I agree 100% with TungstenAudio's comments on the smaller electro bypass output cap together with the existing film type bypass cap, maybe the pcb might have to be slightly longer to allow for that.

Also can you post your existing schematic for this proposed design as it stands at the moment, thanks.

Gary..

Hello Tugnsten and Gary,
thanks for the comments.
It is simple enough to incorporate the option.
Sch needs a bit of clean up, I will post later.

regards
prasi

That was quick prasi, you don't muck around, schematic to come will be OK - no problem at all.

I like the features of the board. Increasing my order to 4, enough for two pairs of mono blocks

Looks beautiful Prasi. Congrats!

I have a couple of variants of the active bridge boards from you, can you tell me which model MOSFETs are recommended? One is a double and other is a single.

Thanks,
X

Hi X,
Here's my selection

 

[prasi]

Hello x,
For the single, Danny's recommendation is good. For the double, you might already having in stock. SQJB00EP
here is the sch for the single and double version.

Regards
Prasi

Thank you, Danny and Prasi.

Very interested in a new CRC+LT4320 PSU.
Also looks more compact than CRCRC PSU (for obvious reasons).

Ok, I want to place the order for the pcbs by thursday / friday, as I will be away for an overseas tour on saturday for 2 weeks.
So, by the time i return and get back to my routine, I will have pcbs in hands.

So I want to close taking requests for the GB by Friday.

regards
Prasi

 

[jimk04]

Can we assume the boards will come at a ' reasonable' price? I know you have offered PCBs at very attractive prices before. I just would hate to have to pull out of the GB if they were a lot more than I expected.
Can you give us a 'ball park's estimate of costs?

Thanks

 

[prasi]

It will be about 6.5 usd a piece, though i am yet to get an estimate from board house.
S&H, paypal+ taxes extra. So for 2 pcbs, you can expect about 19-21 usd all inclusive.
specs: 2.4mm fr-4, 70um copper, double sided, white silk and green mask, HASL.

 

[jimk04]

That's fine thankyou

I don't really care what colour they are as long as they work.
