TPS54336A: Max Duty cycle

Part Number: TPS54336A

Hi team,

May I know the maximum duty cycle of TPS54336A? Can it work on 100% PWM?

Thanks!

    Hello Rayna,

    Yes, as shown in datasheet, 0% off time as long as Boot cap voltage (Vboot-Vph)≥3V.

    But long-time high-side FET on, boot cap will be discharged to below UV threshold. So still you will see SW pulses to charge boot cap.
