Part Number: LM5026EVAL Other Parts Discussed in Thread: LM5026 , UCC2897A
Hi TI Team,
I'm trying to simulate LM5026 EVAL BOARD (hence LM5026) in PSpice for TI (17.4) and I followed the instructions according to the document in the zip file. I configured…
Hi Irene!
Per Figure 18 shown above, this depends on your UVLO pin voltage (which depends on your input voltage). If your UVLO pin voltage is 1.25V - ~2.25V the max duty will be set by the resistors around the DCL pin, if the UVLO pin voltage is greater…
Part Number: LM5026EVAL Hello
I would like to control the controller of the eval board converter from the comp pin, in open loop, skipping the compensator.
So I have removed the optocoupler from the PCB and connected a voltage supply to com pin. The…
Hello Irene,
The capacitors C19, C20 are actually solid tantulum capacitor Vishay 594D series. The full part number is 594D337X96R3D2T. The Kemet part in the BOM is discontinued and this is the replacement part now used .
You should synchronise…
Part Number: LM5026EVAL Other Parts Discussed in Thread: LM5026 Hi friends
I have a doubt regarding LM5026 Evaluation board. In LM5026 Evaluation board the output current is limited to 33A(Hiccup over current).
There is no current sensing at output…
Hello Sophia,
You should put this request through your local TI sales office.
Request that an AE be assigned to this problem and describe the issue and the testing that you require on the LM5026EVAL.
Regards
John
Hello Johnny,
You can reference the LM5026EVAL design which has a 100W rating and the PMP11478 which has a 30W rating. These designs are located on on the LM5026 web page https://www.ti.com/product/LM5026 .
You can use these designs as a starting…
Hello Mark,
The LM5026 does not have ant integrated OVP function so if you wish to use this part you will need to design in an external OVP circuit. The UCC2897A has an integrated LINEOV function that shuts down the controller in the event of an overvoltage…
Hello Chuck,
I'm testing on prototype board for +5V output that it is similar as reference design as link: www.ti.com/.../lm5026eval
There are some things wrong that can't output 5V. I will update the schematic later. This is very challenge to me…
