Part Number: TPS543C20EVM-869 With regard to TPS543C20EVM-869, 80-A Dual Phase Stackable Evaluation Module, I notice its default output voltage is set to 0.9V for this evaluation board. If I order this evaluation board, is there a way to change a resistor…
Part Number: TPS543C20EVM-869 On the TPS543C20EVM-869 User's Guide (SLUUBL7), there are transient response waveforms. The load condition is 25A step and slew rate is 30A/us.
How could you achieve this fast slew rate with EVM? Please let me know the…

Have you looked at the 12V to 0.9V @ 80A 2-phase EVM - https://www.ti.com/tool/TPS543C20EVM-869 ?
It can be modified for for a 0.72V output, and for a 20A/phase full load, lower current rating inductors could be selected, but it does…

1MHz is the upper limit specified by datasheet, but I would not be too concerned if the clock source is ~tens of kHz on the high side above this. It is not a hard limit where the part will simply not function with a slightly higher clock…
Hi Shay,
Does yellow indicate DNP/Do not populate components?
The resistor divider values look correct. With 0.9V reference selected (51.1kohm on VSEL pin), the shown resistor divider of 8.66kohm top resistor and 28kohm bottom resistor will give an…
Hello,
There is a userguide for TPS543C20EVM-869 ( www.ti.com/.../sluubl7.pdf) . It has the load transient waveform.
To achieve +/- 20mV specification, there are other factors to consider: inductance, efficiency, switching frequency...
The datasheet…
Hi Yuto-San,
Below are my comments.
Is it ok to understand that it is not possible to change the reference voltage of the device by changing the resistance value of the VSEL pin?
Saket: Yes.
When changing Vout, is it only to change the resistance…
