LT4320 based active rectifier

[prasi]

Hello
I just recently got a new batch of LT4320 CRC PSU PCB's manufactured, and I have about ~70 of them.
However I have a few of LT4320 THT (8 pairs) and SMD (20 pairs) remaining. I don't have plans to produce them further unless there is a significant demand.
FYIP

Hi Prasi,

Are the LT4320 CRC PSU PCB's manufactured with 2oz copper?

Best,
Vunce

There is an edit in above post.
LT4320 THT rectifier -10 pairs
LT4320 SMD rectifier- 50 pairs

Hello Vunce,
Yes those are 70um thick copper, 1.6mm thick FR-4 material green mask.

Hmmm how can I order ?
Would take 10 of the smd rectifiers and perhaps 2 of the psus... What was the price of those psus ?

hello,
sorry to all for not having reponded earlier.
PCB's have long been ordered and under production as I post.
Once they are delivered to me , I will start sending PM.
I ordered as follows
1. CRC PCBs- 70 nos. (specs-104x 147mm, 2.4 mm thick, 35um, HASL, green mask, price 6.5 usd a piece)- earlier it was 70um but same price
2. THT PCBs- 64 pairs (specs-32.5x 55mm, 2.4 mm thick, 35um, ENIG, green mask, price 3.5 usd PER pair) - earlier it was 70um but same price
3. SMD PCBs- 200 pairs (specs-30.48x 30mm, 1.6 mm thick, 70um, ENIG, green mask, price 2.5 usd PER pair) -earlier it was 2 USD same specs

please note following for Sr. 2.
The boardhouse no longer has 2.4mm and 70um material. so THT PCB are 35um. please note.
If someone requires only 70um in THT, then they will have to wait for the next order where I could order in 1.6mm thick, 70um ENIG.

The reason for delay is that I was trying to get a best price (2 rounds of negotiations) and also looking for material availability of 2.4mm thick in 70um for Sr. 2.. Alas the material is no longer available with boardhouse and no timeline of when it will be available.

above are the prices.
for CRC PSU PCBs, the new specs are 1.6mm thick FR4, 70um copper, green mask, price is same.

You may write your name and requirements in the above list and share your PayPal email via PM. I will send a PayPal invoice and once the invoice is paid, I will ship pcbs via tracked post.

What is the limit for transformer voltage for the LT4320 CRC PSU PCB?

 

[prasi]

72 VDC is absolute limit. transformer should not exceed ~48-50VAC . you need to adjust other component ratings according to your voltage.
