UCC28951: UCC28951 turn off delay time

John Hsiao

Part Number: UCC28951

When UCC28951 pin 5 SS/EN below 0.55V turn off threshold, what is the propagation delay time(max) to turn off PWM gate control signal? Thanks.

Hi John,

Please let us look into your question regarding the propagation delay and get back to you.

Hi John

The OUTx pulses cease immediately and asynchronously as EN passes through the threshold. The propagation delay would be less than 1us

This is not a measured parameter. Please note that I took the image below without a SS capacitor.

Please let me know if you need more details. (please let me know if there is no image below)

Colin
