Figure 1 -- Basic module operation requires fusing, grounding, bypassing capacitors.* See Maxi, Mini, Micro Design Guide. Output Connections and Considerations 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. 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.

This may be done with an open collector transistor, relay or optocoupler. Multiple converters may be disabled with a single transistor or relay either directly or via "OR'ing" diodes. See Figure 2. 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, overtemperature) 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 Auxiliary Supply At 5.7V, PC can source up to 1.5mA.

All PR pins are connected to a single communication bus through 0.001F (500V) capacitors. This interface supports current sharing and is fault tolerant except for the communication bus. Up to three converters may be paralleled by this method. See Figure 9. Output Voltage Programming The output voltage of the converter can be adjusted or programmed via fixed resistors, potentiometers or voltage DACs. See Figure 8. Transformer-coupled interface. For paralleling four or more converters a transformer-coupled interface is required, and under certain conditions a PR buffer circuit. +OUT +S Error Amplifier For details on parallel operation please refer to the Design Guide & Applications Manual for Maxi, Mini, Micro Family.

Hence, available output power is reduced by the same percentage that output voltage is trimmed down. Do not exceed maximum rated output current. The trim-down resistor must be connected between the SC and -S pins. Do not bypass the SC pin directly with a capacitor. Parallel Bus Figure 9 -- AC-coupled single-wire interface * See Maxi, Mini, Micro Design Guide The converter is rated for a maximum delivered power. To ensure that maximum rated power is not exceeded, reduce maximum output current by the same percentage increase in output voltage. 4.7nF T1 4.7nF T2 PC PR Module 1 0.2F R1* +IN PC Module 2 PR -IN Parallel Bus Trim resistor values calculated automatically: 4.7nF Figure 10 -- Transformer-coupled interface Number of Converters in Parallel *R1 value 2 75 3 50 4 33 5 or more refer to application note: Designing High-Power Arrays using Maxi, Mini, Micro Family DC-DC Converters The PR pin supports paralleling for increased power with N+1 (N+M) redundancy.
