Part Number: DRV8353RS-EVM
Dear sir,
I have DRV8353RS-EVM , LAUNCHPAD-F280025C and Hub motor .
(Note:- I am using 24 to 30 volt power supply and my hub motor max voltage are 48 volts and 102 hz frequency)
Recently I have complete the DMC_Level_1 as per…
Part Number: TPA3255
I have been a happy user of my custom made TPA3255 boards for years now and still am, despite a recent incident at high volumes . I have a MCU in the front end that detects clipping/error conditions and lowers the volume when clipping…
I used your config file and waveform, and I got much better ACLR of better than 45dBc.
But somehow the waveform BW is 40MHz.
I am not sure what is wrong, but I got good ACLR so I could try my next stage test (EVM test).
I will generate waveform by myself…
Hi James,
I used the EVM to do test and found that PVIN will generate an Inrush current when VDDQ power on. As the VDDQ frequency increases, the current will surge.
This is how I connect:
This is the waveform at startup using a linear power supply to…
Hello Faisal,
Please see this recent documentation regarding using decompensated op-amps in unity-gain configurations. If you have further questions or want to discuss a part you found to use instead of the OPA690 SOT23, please let me know.

Part Number: BQ25756 Hi All,
In the datasheet (and EVM), the system load can be fed both from the battery and the BQ25756 as it is parallel to them.
In my case, the main load are BLDC motors that can draw up to 30 Amps.
The solar charger that is connected…
Hi Lauren,
What's your test condition? Input voltage, load current?
I made the same change on our EVM and found the frequency is ~600k under 12Vin 0.6A loading. However, if you increase the loading you can find the frequency becomes normal.
That's…
Part Number: DRV8662 Other Parts Discussed in Thread: TINA-TI , DRV2700 Hello!
I am trying to simulate the DRV8662 in MATLAB Simscape. The first step of this process requires converting its TINA-TI model to a generic SPICE model, as described in this …
Hi Ted,
I do not know of a similar op-amp that we could borrow the spice model of. What you could do is use the generic op-amp model and input the relevant information from the datasheet to be able to run the stability simulation.
I can also sample you…
Part Number: UCC28951 Other Parts Discussed in Thread: UCC28950EVM-442 , UCC28950 , TINA-TI Hello,
I am working on design of 2.5kW 48V PSFB DC-DC converter using UCC28951 Controller IC. (input voltage: 370 to 410 Vdc)
We tested using on-board UCC28951 IC…
