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.

This may be done with an open collector transistor, relay, or optocoupler. Converters may be disabled with a single transistor or relay either directly or via “OR’ing” diodes for 2 or more converters. See Figure 2. Primary Auxiliary Supply During normal operation only, the PC Pin can source 5.7V @ 1.5mA. In the example shown in Figure 4, PC powers a module enabled LED. Module Alarm The module contains “watchdog” circuitry which monitors input voltage, operating temperature and internal operating parameters. In the event that any of these parameters are outside of their allowable operating range, the module will shut down and PC will go low. PC will periodically go high and the module will check to see if the fault (as an example, Input Undervoltage) has cleared. If the fault has not been cleared, PC will go low again and the cycle will restart. The SC pin will go low in the event of a fault and return to its normal state after the fault has been cleared. See Figures 3 and 5. Primary Control - PC PIN

• The +OUT and –OUT power buses should be designed to minimize and balance parasitic impedance from each module output to the load.
• The +Sense pins must be tied together to form a +Sense bus. This must be Kelvin connected to +OUT at a single point. The –Sense pins should be tied together to form a –Sense bus. This must be Kelvin connected to –OUT at a single point.
• At the discretion of the power system designer, a subset of all modules within an array may be configured as slaves by connecting SC to –S.
• OR’ing diodes may be inserted in series with the +OUT pins of each module to provide module output fault tolerance.
• The +Sense and -Sense leads should be routed in close proximity to each other on the printed circuit board. If wires are used to connect the converters on a PCB to an external load, the Sense leads should be twisted together to reduce noise pickup.
