Other Parts Discussed in Thread: TPS62130A-Q1, , TPS62902-Q1, TPS62903-Q1, LM61430-Q1
Webench shows me below comparison results:
- LM61430AAS-Q1
Efficiency: 91.9%, Switching Freq: 2.17 MHz.
- TPS62130A-Q1
Efficiency: 89.9%, Switching Freq: 1.34 MHz.
I don't understand why the efficiency of TPS62130A-Q1 is lower than LM61430AAS-Q1 nevertheless TPS62130A-Q1 is working at lower frequency.
And, I want to know the generated noise profile or some tendencies when I use above 2 regulators.
Additionally, I want to avoid AM band.
I'd like to know what kind of problem will occur when I don't consider about AM band.
