Output Connections and Considerations
The permissible load current must never be exceeded during
normal, abnormal or test conditions. Converters subject to
dynamic loading exceeding 25% of rated current must be
reviewed by Vicor Applications Engineering to ensure that the
converter will operate properly.
Under dynamic load, light load, or no load conditions, the
converter may emit audible noise. Converters that utilize remote
sense may require compensation circuitry to offset the phase
lag caused by the external output leads and load impedance.
Remote Sense leads must be protected for conditions such as
lead reversal, noise pickup, open circuit, or excessive output lead
resistance between the sense point and the converters output
terminals. For applications that may draw more than the rated
current, a fast acting electronic circuit breaker must be utilized
to protect the converter. Under no circumstance should the
rated current be exceeded. Utilizing or testing of current limit or
short circuit current will damage the converter. Ensure that the
total output capacitance connected to the converter does not
exceed the limits on Page 16, “Maximum Output Capacitance”,
of the design guide.
