LT4320 based active rectifier

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

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

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

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

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

Hi Prasi, can they be red with square corners ?
