TPS628510: PWM and PFM conversion threshold

Part Number: TPS628510

Hi Team,

May I confirm the PFM threshold of TPS628510? How can I understand the below yellow highlight part? Is the PFM and PWM threshold the same as the CCM/DCM boundary?

Best Regards,

Jaden Yue

    Hello Jaden,

    Thank you for reaching out,

    When the peak inductor current is above 0.8A, the device operates in PWM mode and if the peak current of the inductor is less than 0.8A then it operates in PFM mode.

    Yes, those are similar.

    Thank you & regards
