FEATURES:
The QP Series of Miniature Power DC/DC Converters operates over wide
input voltage ranges (4.59Vdc, 918Vdc, 18 36 Vdc, and 36 72 Vdc)
while maintaining tight output regulation and low ripple.
Safety Features of QP Modules include: Overtemperature, Input
Under/Over voltage, Output Overcurrent and Short Circuit Protection.

External Bias Function
Ex.B Voltage = 17...20Vdc; Ex.B Current = 20mA (typical)
External Bias should be used in Capacitor Charging applications. The QP unit will not startup under a shortcuicuit condition because the Internal Bias
Supply cannot develop the required startup 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.
