CONTROL FUNCTIONS - PC PIN
Module Enable/Disable The module may be disabled by pulling PC below 2.3V with respect to the -Input. 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 1. Primary Auxiliary Supply At 5.7V, PC can source up to 1.5mA. In the example shown in Figure 3, 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, 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 2 and 4.

Figure 7--Output voltage trim down circuit. Trim Down 1. This converter is not a constant power device - it has a constant current limit. Hence, available output power is reduced by the same percentage that output voltage is trimmed down. Do not exceed maximum rated output current. 2. The trim down resistor must be connected to the -Out pin.
Figure 8--Output voltage trim up circuit. Trim Up 1. 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. 2. The trim up resistor must be connected to the +Out pin. 3. Do not trim the converter above maximum trim range (typically +10%) or the output over voltage protection circuitry may be activated.
Trim resistor values calculated automatically:
On-line calculators for trim resistor values are available on the vicor website at: vicorpower.com/tools.html. Resistor values can be calculated for fixed trim up, fixed trim down and for variable trim up or down cases for both 1st and 2nd Generation DC-DC converters. In addition to trimming information, the web site and the Applications Manual also include design tips, applications circuits, EMC suggestions, thermal design guidelines and PDF data sheets for all available Vicor products.

CONTROL FUNCTIONS - PR PIN
Parallel Operation The PR pin supports paralleling for increased power with N+1 (N+M) redundancy and phased array capability. Modules of the same input voltage, output voltage, and power level will current share if all PR pins are suitably interfaced. Compatible interface architectures include the following: DC coupled single-wire interface. All PR pins are directly connected to one another. This interface supports current sharing but is not fault tolerant. Minus In pins must be tied to the same electric potential. See Figure 9. AC coupled single-wire interface. 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. See Figure 10.

* The +Out and -Out power buses should be designed to minimize and balance parasitic impedance from each module output to the load. * At the discretion of the power system designer, a subset of all modules within an array may be configured as slaves by shorting SC to -Out. * Do not use output OR'ing diodes with MicroMods.
