Part Number: UCC28630EVM-572 Other Parts Discussed in Thread: UCC28631 , UCC28630 , UCC28634 Dear TI,
I am trying to design a housekeeping power supply for one of our products.
Requirement:
Input: 260 Vdc to 710 Vdc
Output: 12 V @ 1.5 A max.
I am using…
Other Parts Discussed in Thread: UCC28630EVM-572 Dear TI Engineers,
I have to use UCC28630EVM-572.
The important element NG occurred during testing .
NG Part
MOSFET -> 683V( @264Vac Turn on )
2 nd Rectifier -> 126V( @264Vac Turn on )
Efficiency…
Hi Rishav,
Thank you for the query about UCC28633.
I would suggest starting with the following reference designs to get started with UCC28630EVM-572 , PMP30092 & PMP9643 to start with in addition t o the specific ation from WEBENCH designer.
1. The above…
Hi, Wouter:
The file you shared shows blank in the red area. Would you please check it again?
RBLB means the preload (or dummy load) which is "necessary" to be used in output side because it is a PSR topology.
For example, you can refer t…

Best place to see what expected waveforms for UCC28630 is the EVM http://www.ti.com/tool/UCC28630EVM-572 . The user guide for this EVM has typical waveforms http://www.ti.com/lit/ug/sluuax9b/sluuax9b.pdf?ts=1590872018331 . If it does not include a specific…
Hello Peter,
Sorry for my late reply; I couldn't get back to you earlier.
I am a bit confused at this point. What EVM are you using? I assume maybe the UCC28630EVM-572, modified with a UCC28631 at first, then later with a UCC28634?
I'm still not…
Hi Akash Jain,
I suggest you use the EMI filter design used in the UCC28630 EVM, www.ti.com/.../ucc28630evm-572
This will act a s a starting point for your design.

Dealing with electrical noise that is generated from the harmonics of the switching frequency is a common challenge in switched mode power supply design. For high voltage input designs, which UCC28630 targets, this noise can be even worse sine the…
Hi Manu,
We do provide transformer design for many of our designs. Below are some designs where we have transformer design available for a 65W converter using the same part family UCC28630.
