Pin and baseplate style may vary. Pin style 1 and slotted baseplate are shown.) Product Overview This DC-DC converter module uses 2nd Generation power processing, control and packaging technologies to provide the performance, flexibility and cost effectiveness expected of a mature power component. For example, a plated-cavity core transformer couples widely separated primary and secondary windings, resulting in low in-toout parasitic capacitance and noise. High frequency ZCS/ZVS switching, advanced power semiconductor packaging and thermal management provide high power density with low temperature gradients. Extensive use of silicon integration results in 1/3 the part count of a 1st Generation converter. This converter is manufactured in a state-of-the-art automated manufacturing facility on a short-cycle-time robotic line having a capacity of one module every ten seconds. In-line process controls are designed to achieve low defect rates and consistent quality. A comprehensive CIM system controls the dispatching, assembly and testing of each module, enabling small lots to be manufactured as efficiently as hundreds-of-thousands of units.

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.

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. 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 +Sense pin. 3. Do not trim the converter above maximum trim range (typically +10%) or the output over voltage protection circuitry may be periodically 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.

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.
