**Part Number:** LM5060-Q1

Hello TI experts,

We’re reviewing the OVP calculations of LM5060-Q1 and have some questions as below. Could you please help check and reply to us?

Thank you.

- The R3 resistor calculation formula might have problem in the datasheet, it seems comes a negative value by calculation. Could you please help take a look?

- Can we use the below formula VINmax in datasheet for calculating the OVP limit? Also can we exclude the UVLObias parameter in the calculation?

- There is a hysteresis of 240mV for OVP, how does the OVP work with this hysteresis?
- The behavior, for example a 17V OVP setting, when the input over 17V, the OVP is active to turn off output, and while the input voltage fall down below 16.76V(17V-240mV), then the output will come back, right?

- Have you ever met or had any lesson learn that the practical OVP active point below the OVP calculation point?

- What’s the difference between
**OVP**bias and**UVLO**bias? From the datasheet block diagram, I do not find where is OVPbias current, what’s it’s function and effect?- When we design OVP, shall we consider both of them or only UVLObias current as spec formula is enough?
- In the TI calculation tool, it only considers UVLObias without OVPbias. Why OVPbias is not considered?
