Hi,
Looking for T2 Transformer details ... BOM and Schematic do not have any details.
Also "Excel Design Tool" for this design will help.
Hello Ninomiya-san
A4/ Switching at 300kHz is possible - the PMP20657 runs at this speed - http://www.ti.com/tool/PMP20657
A5/ The LMG3411R050 device can be used with the UCC28951(0) - The LMG3411R050 includes on-board drivers. The 0/10V output…
Hi David,
Radj is between Vout+ and Sense+, nothing else. If you measure the resistance you will read Radj. Sense+ is the feedback signal to the compensation network on UCC28951. If I plug Radj as Rsense in the Excel sheet, I get nonrealistic values…
Hi Ramar,
The UCC2891 is designed for active-clamp forward topologies. In the table below, ACF topology is typically used to ~400W.
It's probably best to use a half-bridge or phase-shifted full-bridge topology.
Here are two reference designs that…
Hello,
I do not know of the UCC28950 or the UCC28951 being used in a bidirectional power supply.
There is an application note that goes through the step by step design process of a PSFB using the UCC28950 and UCC28951 PSFB converters.
However…
Thanks for the response, Ben. I'm not a power engineer (digital), and topologies beyond basic buck/boost are outside of my realm of knowledge.
I should have mentioned in my OP, full isolation is a requirement here... a quick glance at the schematic…
Hello Sanjay
I'd suggest that you use the UCC28951 instead of the UCC28950. The UCC28951 is a newer drop in replacement device that works better when operating simultaneously at Dmax and in current limit.
The easy question first: yes, you can certainly…
Other Parts Discussed in Thread: UCC28951 , PMP20657 , PMP6712 , LM5122 , LM5045 , UCD3138 Hello,
We need to choose a right topology and appropriate controller for one of our projects with the following specs: Does anyone have any suggestion/recommendation…
