UCC28019A: UCC28019A standby power

Wei-Hao Chen (TW-FAE)

Part Number: UCC28019A

Hi team,

My customer is interested in what is the standby power can UCC28019A achieve during no load? any reference design to show standby power the data?

And what would be the standby power difference in mW when UCC28019A is operating under normal mode & user selected standby mode by pulling the Vsense lower than 0.8V?

Thanks.

Best Regards,

Hello Wei-hao,

On a 350W design the standby power draw is about 630mW at 115Vac input.
The UCC28019A will draw and additional 12V at 5mA.

With VSENSE pulled to ground disabling the pfc, then the power supply standby power is about 43mW with an additional power of 12V 2mA required for the UCC28019A.

These numbers will be higher as the input voltage increases.

Regards

John
