TPS7H5004-SP: RT Tolerance in Externally Set Frequency Tolerance

Syler Huang

Part Number: TPS7H5004-SP

Tool/software:

We are performing a switching frequency analysis on the TPS7H5004-SP.

Does the RT tolerance included in the external set frequency tolerance in the datasheet? If so, what is the tolerance of RT for the tested external set frequencies?

Best regards

Hey Syler,

The RT resistor should be depopulated if you use an external clock.

Thanks,
Daniel

I am not using an external clock. RT is used to set the frequency.

I want to know what's the tolerance of these RTs while testing the frequencies.

Hey Syler,

The RT resistor doesn't change between tests, the parts get put on the same test board.

Thanks,
Daniel
