Hi, John
Thans for response.

For TPS92200D1, it is listed as 0.65V~1.2V, but for TPS92200D2, VDM_H is only 0.65V(min), so I asked.
If so, can I understand that TPS92200D2 can…
Part Number: TPS92200D2EVM Other Parts Discussed in Thread: TPS92200 I am using the TPS92200 and I would like to use the D2 version as I am usually able to provide a DIM signal around 20 KHz, which is fast enough to take advantage of the PWM-to-analog…
Hi Warren,
You can refer to this E2E thread - TPS92200D2EVM: About the value of Rfb - Power management forum - Power management - TI E2E support forums .
Hope this helps. Let me know if you have any other question.
Best Regards,
Steven

Hi Ryusuke,
R4 is used to measure the loop response. It is not necessary if you do not measure the loop response.
I would recommend you switch to the next generation of TPS54200, which is TPS92200.
You can refer to this thread for more detailed information…
Hi Kok,
Kok Khuan P'ng said: There is another oscillation at around 1.6kHz, which can be solved by placing the 10uF 50V capacitor across output and FB instead of placing it across output and GND.
Does this 1.6kHz oscillation also exist when the load…
Hi Sean,
Currently, we are using TPS92200D1 for the test. I just placed an order for TPS92200D2EVM to do more tests and it should arrive tomorrow.
BTW, the analog dimming mode also uses PWM signal from our MCU side, right?
Thanks,
Alan
