Hi,
Looking for T2 Transformer details ... BOM and Schematic do not have any details.
Also "Excel Design Tool" for this design will help.
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, the application…
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…
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 for…
Part Number: UCC256404 Other Parts Discussed in Thread: UCD3138A , UCC256403 , PMP3162 , PMP20657 , UCC2897A Efficiency is of high concern for my current design, hence the choice of a resonant LLC. Despite the datasheets not providing any evidence a low input…

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…
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 of the…
Part Number: UCC28950 Other Parts Discussed in Thread: UCC21521 , UCC28951 , PMP20657 Hi,
I am in the paper designing stage to develop a 960W phase shifted full bridge with zvs using ucc28950. I am referring to app note SLUA560C for the same. A PFC pre…
