TPS25830A-Q1: Cable droop compensation voltage variation

Kiyoshi Koyama

Part Number: TPS25830A-Q1

Hello support team,

I would like to know about cable droop compensation voltage variation.

The IMON pin voltage variation can be confirmed in the EC table below, but the actual CSN/OUT compensation voltage variation could not be found.

Thanks,

Hi,

You can find compensation voltage on Figure 8-18 and 10.3.12 Cable Compensation. It should be very clear for descripting cable compensation.

Regards,

Ansel

Hi, Ansel

Thank you for your reply.

But what I want to know is the output voltage accuracy including cable droop voltage compensation.

The EC table says that the IMON voltage accuracy is +/- 65 mV, but I'm wondering if the actual output voltage accuracy will be a little worse.

Thanks,

Hi, Kiyoshi,

The CSN value with cable compensation will be 5.1V + VIMON. So the actual output voltage accuracy will not be worse.

Thanks.

Bob
