Part Number: TPS2660

About TPS2660 datasheet P17, I think that RTN is internally connecting to GND.

Is there wiring resistance data for RTN to GND line?

OVP and UVLO calculation are a little influence RTN to GND wiring resistance(voltage drop), I want to know these minute error.

Best regards,

Hi Satoshi,

Internal resistance from RTN to GND is 10 ohm and the voltage drop due to Iq current would very minimal, of the order of mV.
300uA and 10ohm would give 3mV.

Regards,
Kari.
