    Hi Yoshiki Ochi, 

    Thank you very much for reaching out.

    Yes, you can maintain a 100% Duty Cycle in VDRV by placing EN high. Just to clarify further, the Duty pin in TPSI3050 refers to the Power Transfer from Primary to Secondary. This pin does not control PWM duty cycle on the VDRV pin. If you would like to have a 100% duty cycle in VDRV, you will need to place EN high 100% to assert VDRV high 100%. 

    Let us know if this answered you thread. 

    Sincerely, 

    Francisco Lauzurique
