I was able to start with a clean new Ubuntu 22.04 LTS VM. I then downloaded in installed: CCS 12.0.0, MCU+ SDK AM64x 9.01.00.41, SysConfig 1.18.0, Clang compiler 3.2.0 All in ~/ti When I tried to import an example from the SDK, I got the below error: This is interesting because my warning is different than yours. The CCS import wizard is looking for a specific string for the 3.2.0 compiler (TICLANG_3.2.0) and can't find it so it defaults to a different 3.2.0 string (TICLANG_3.2.0.LTS) which is discovered. When I check my workspace folder, I see that the project folder for the example exists in there. Then when I build the project, it will actually build correctly since it is using the TICLANG_3.2.0.LTS it discovered. There is some mismatch with the names but it is not impacting my build. e2e.ti.com/.../4505.build_5F00_log.txt The question is why you cannot even get to this point. One thing I would like to confirm is if you resolved all the dependencies mentioned in: https://software-dl.ti.com/ccs/esd/documents/ccsv12_linux_host_support.html If so, then can you try importing the same SDK example I imported in: ~/ti/mcu_plus_sdk_am64x_09_01_00_41/examples/empty/am64x-evm/r5fss0-0_nortos/ti-arm-clang Do you have the same issue?

Hi Jonathan, Are they trying to simulate a test circuit built into PSpice for TI? They'll need to archive and post the project for verification and trouble-shooting. David

Forum Post: RE: LM25149-Q1: simulation not enabled for this design
Hi Malakondareddy, In order to expedite your request, please fill out the calculator tool and attach it everything in there should help you design your system. https://www.ti.com/tool/LM5149-LM25149DESIGN-CALC To answer your question about the input filter, Assuming the input power supply is an ideal voltage source the device will behave normally with or without a filter. However, LM25149 may add EMC or conducted emissions to everything else connected to that voltage source if there's no filter at the input. Thanks, Andrew

Hello Vitalij, I'm sorry but, No, we do not have the UCC28070 modeled in Multisim. The only models we have available are listed here: https://www.ti.com/product/UCC28070#design-tools-simulation Regards, Ulrich

very bad very bad very bad Why didn’t they design the frequency regulation for this chip so that it could be used at low loads and at the same time be used at high loads???? Thank you.

Forum Post: RE: Форум по управлению питанием
Hello Vitalij, I don't understand your question. The UCC28070 is a PFC boost-controller and regulates output voltage, not frequency. The voltage is regulated at low loads as well as high loads. The switching frequency is fixed value that is chosen by the PFC designer. Regards, Ulrich

Could you share the schematic? Did you power up it with no load? what's the input voltage? what are the waveforms for the there channels?

Forum Post: RE: PMP41009: UCC28740-Q1
Hi Linda I connected an LDO after the 12V output(CH2), and CH3 is the output of LDO. yes I power up it with no load. The switching frequency is stable when unloaded. The schematic is showen below.(The actual resistance and capacitance values on the board may differ slightly from the schematic)

Forum Post: RE: TIDA-01292: TIDA-01292
Hi, You may see TIDA-010292 is a power design for low frequency offline UPS. It has a lot of design considerations and calculations on FET driver, sensing, control, etc. While the transformer is a normal 850VA 50/60Hz transformer which we didn't put a lot documents. I tried to reach out to the designer but seems he left. To better support you, you may look at below more designs: TIDA-010938; TIDA-010933 both are common used in energy storage systems. Thanks.

Forum Post: RE: TIDA-01385: Design of a self powering AC current sensor
Hi Jonas, Apologize for the late reply. It took us a little time confirming the responsible organization for this design and now I'll be taking this thread. It'll need extra iso circuit to sample the AC secondary current because the CT (VAC1,VAC2) is not common grounded with your control circuit: So there're several ways to sample the AC current: 1.sample the rectified current to calculate the RMS value. This will be a rough sampling because of the Vf of the rectifier diodes. But this rectified current can be measured on the same ground with your MCU so you won't need isolation circuit. 2. The other way is to apply an hall IC. 3.You can replace the hall with an isolated amplifier, but an isolated amplifier needs power rail for both front side and back side so this will be the hard way: Best Regards, Travis

Forum Post: UCC3895: Using the UCC3895 below 50kHz
Part Number: UCC3895 Other Parts Discussed in Thread: UCC2895 , UCC28950 Tool/software: UCC3895/UCC2895 : Phase Shift Full Bridge Hello, I'm using the UCC3895 for a PSFB with high voltage ratio x30. The frequency is arround 20kHz for the application. I've done the simulation with PSpice for TI and it works well. However, in the datasheet, the minimum frequency of the IC is 50kHz. Is it physically problematic if I use it at 20kHz. In advance, many thanks for your return.
