This may be done with an open collec- tor 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 5.7 V, PC can source up to 1.5 mA. 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. +IN PC PR –IN Disable Disable = PC <2.3 V Figure 1 — Module enable/disable.

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 +Sense pin. 3. Do not trim the converter above maximum trim range (typically +10%) or the output over voltage protection circuitry may be activated. CONTROL FUNCTIONS - SC PIN 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 –Sense pin. Trim resistor values calculated automatically: On-line calculators for trim resistor values are available on the vicor website at: vicorpower.com/tools. Resistor values can be calculated for fixed trim up, fixed trim down and for variable trim up or down. 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.
