TPS54201: Pole frequency doesn't reach the recommended values

Jens Pauli

Part Number: TPS54201

Tool/software:

Hello everyone

I'm using the TPs54201 as a Peltier driver and I'm trying to get to the recommended pole frequency of 2kHz (analog mode) with parts which are already used in the project to save cost.

With the parts we have a already in use, i can get to around 1.5-1.6kHz instead of 2kHz. How will this influence the TPS54201?

Hi Jens,

Glad to help you here!

Considering the pole is very close to the required value, it is quite safe. No obvious will show.

Could you please kindly share the end-equipment application of Peltier you made and the run rate please?

Thanks a lot!

Best,

John.
