External Bias should be used in Capacitor Charging applications. The QP unit will not start-up under a short-cuicuit condition because the
Internal Bias Supply cannot develop the required start-up voltage. To charge up a large capacitor, an external bias voltage should be used only
until the output voltage, Vout, reached 90 - 95% of its nominal value and therefore the internal bias voltage has come up and is able to sustain
converter operation.
Note that during External Bias operation, output overload and short circuit protection are disabled and for this reason it is highly
recommended - as shown in diagram - to disable the External Bias supply after Vout reaches its nominal value and allow from that moment
on for the internal bias voltage operation. While on internal bias operation, overload and short circuit protections are restored.
For additional information, see Application Notes.
