The BP62640 is an AC/DC secondary-side controller thatpairs with the BP87640 to achieve zero standby power intravel adapter applications.The BP62640 employs an output voltage ripple-basedcontrol algorithm that allows for fast transient responsewhile eliminatingthe need for complex loop compensationcircuits.BP62640 sends request signals to the primary-sidecontroller through the magnetic coupler BP818 to realizethe regulation of the output voltage.
