LT4320 based active rectifier

[prasi]

Hello All,
I have received the PCBs the LT4320 last week, but due to other commitments, I couldn't post here and start sending out paypal invoices.

Now I will begin to do so . Will send out 6-8 invoices a day, so that there are no mistakes and postal logistics and packaging/labeling is easily manageable.

I might take a break from this activity for 1-2 days depending upon my "work". Lot of travelling and site visits these days 😱

I will keep updating the google sheet on the status ( invoices sent status / payments received / shipping status).
Please do check the sheet from time to time for your update. I might be a bit late to answer here or via PM.

Regards
Prasi

P.S.
Thanks Myles. Glad to know that you got all the packages. I havent any that I am holding back right now except for this upcoming LT4320 PCBs.

Yes, we do appreciate the efforts required, as I know personally how time consuming this is.
Thank you, Prasi.

Hi prasi, did you manage to get the first lot posted as you mentioned a few days ago?

 

[prasi]

Hello Manniraj,
Received the payment. I have updated the sheet to reflect the same.

Hello Gary,
I managed to post about 10 packets yesterday. I will update the sheet with tracking numbers soon.

Just curious whether people have started to source the MOSFETs for the assembly of the rectifier. I am at a lost for which one to pick (based on Prasi's suggestion list or otherwise)?

Hello Lo,
My list is to just give an idea on the type of mosfet thats suitable to use on the PCB.
Based on the recommendations of tvicol , pick the one with
1. highest VDs
2. Lowest Rds on
3. Vgsth about 3-4 V
4. Lowest Qg
5. availability and price

My choice is https://www.mouser.in/datasheet/2/408/taiwan_TPW4R50ANH-1209311.pdf

which has
VDS-100V
Rds on-3.7mOhm
Vgsth -2.7 V @40deg.C (VDs-10V, Id-1mA)
Qg-58nC.

Mind you, there may be better ones available.

Regards
Prasi

Out of interest prasi - what would be your choice for the through hole Mosfet, thanks.

Out of interest prasi - what would be your choice for the through hole Mosfet, thanks.

either this one for 100 V VDS - TK65A10N1, or CSD19535KCS or IPP076N15N5AKSA1
or the one you have for 80V VDS- CSD19501KCS

Again , mind you, there may be better ones available.

 

[gary s]

Thanks for your reply prasi, appreciated. I will have a look at the 100V devices you mention. I have the CSD19501 to load on your boards when I get hold of them.

 

[prasi]

You are welcome, Gary,
I had the Sheet updated with shipment tracking numbers for 12 packets.
today if I get some time, i will send out the next batch of invoices.
regards
Prasi
