Part Number: TPS548A20EVM-737 Other Parts Discussed in Thread: TPS548A20 Hi team:
My customer going to use TPS548A20 to drive some RF devices and need less ripple. For the first PCBA , they got roughly 30mV ripple when loading 8A but 1.2Vout(default…
Seems like the output voltage configuration with the TPS548A20EVM-737 is more straightforward, as simple as just changing a resistor. I still don't understand why changing the resistor with TPS53319EVM does not seem to do the same thing.
Yes, RRF is resistors divider ratio and please check table-3 at TPS548A20EVM-737 users guide to select correct resistors for one of eight switching frequencies from 250 kHz to 1 MHz.
as far as table-2, it is not typo. it is bench test data that was taken…
