TPS2662: How to calculate for resistor values for OVP?

Kwan Lee

Part Number: TPS2662

Hi,

How would one calculate for OVP resistor values if OVP will be enabled while UVLO will be disabled by connecting a 1Mohm resistor between IN and UVLO pins?

Thanks,

Kwan

You can use design calc on web and put R1 zero there.

Hi Kunal,

I'm using TPS26620 Design Calculator, but it won't let me change R1.

Which calculator are you referring to?

Hi Kwan,

Please refer this section of datasheet and make R1 zero in equation there.
