UCC28610: How to calculate brown in voltage of UCC28610

Brian Wang0

Part Number: UCC28610

Dear Champs,

For UCC28610, is there a way calculate the bulk voltage when the device start to work?

We understood the working is determined by the voltage on Vdd pin, but is there any way to calculate the bulk voltage at that moment?

Thanks,

Brian

Hello,

I could not find the information in the data sheet but found the information in the excel design tool.

Vin*Na/Np > IVSLrun*RVS1 the controller will know the input voltage is high enough. IVSLrun = 225 uA

The device has histories so the device will stop operating when

Vin*Na/Np < IVSLstop*RVS1, where IVSLstop = 80 uA,

The following link will bring you to the excel design tool.
