Hi TIer,

I have TLV62568 question about Power Save Mode Operation.
1. May I know ring condition reason on Vse in Power Save Mode Operation?
2. When Zero Current Detect inductor current fall to zero, the low side mosfet switch off and into Diode Emulation Mode, right?

Hi John,

The ringing on VSW happens when the output capacitor and Coss of the low-side FET goes to charging and discharging cycle after the inductor is de-magnetize (Icoil = 0) and the body diode of the low-side FET turns off.

Best regards,
