Hi,

My customer want to find a mature 200W AC/DC scheme. Parameters as attachment.

Do we have such mature 200W AC/DC scheme?

Thanks!200W电源规格书.pdf

Hi Rui,

You did not provide any basic information such as VIN, VOUT, IOUT and the .pdf you included is in Chinese, so that doesn't help us.

You know that you can search the power reference designs here: http://www.ti.com/reference-designs/index.html and chances are you will find a Reference Design you can use. Please try this and let us know what matches your requirements, or at least comes close.

Regards,

~Leonard

Hi Leonard,

Customer need a 200W AC/DC scheme, with two channel isolated outputs.

Rated input voltage is 100 to 240V AC. Input voltage frequency is 47 to 63Hz.

The maximum input current is 3A. Efficiency more than 86%.

One channel output voltage is 28V, output current is 7A.

The other channel output voltage is 5V, output current is 2.5A.

Besides, the overcurrent protection need hip-cup mode and two channels need self recover.

Do we have such reference design?

Thanks!

Hi Rui,

Looks like you will have to use two separate designs. Using the Ref Design link I previously provided, there are two Ref Designs for the 28V/7A supply: http://www.ti.com/reference-designs/index.html#search?vinmin=90&vinmax=240&iout=7&vout=28&isolated=Isolated&intype=AC . And for the 5V/2.5A supply, there are 30 to chose from: www.ti.com/reference-designs/index.html#search?vinmin=90&vinmax=240&iout=2.5&vout=5&isolated=Isolated&intype=AC .

You can also start a new design using WEBENCH, and btw, a single supply with the two rails could not be completed using WEBENCH, so again, two separate supplies. Again as an example, for the 28V/7A supply has two WEBENCH solutions, both based on the UCC28600. Is there any reason the customer would not use a new design? What is driving the "mature" requirement?

Hope this has been helpful. I encourage you to explore WEBENCH and Ref Designs for this and future requests. Very useful tools!
