(10,9 mm) Parallelable, with N+M fault tolerance Low noise ZCS/ZVS architecture Shown actual size: 2.28 x 2.2 x 0.5 in 57,9 x 55,9 x 12,7 mm Typical Applications: distributed power; off-line systems using power PFC front ends; electric vehicles Product Overview This DC-DC converter module uses second 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 first generation converter.

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. 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, 4. Primary Auxiliary Supply At 5.7V, PC can source up to 1.5mA.

Figure 8—Output voltage trim up circuit. Trim Down Trim Up 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. 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 down resistor must be connected to the –Sense pin. 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. Trim values calculated automatically: Resistor trim calculators are available on Vicor’s web site at URL: www.vicr.com/tools.html or by requesting a copy of Vicor’s Applications Manual on a CD ROM. 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 on CD ROM also include design tips, applications circuits, EMC suggestions, thermal design guidelines and PDF data sheets for all available Vicor products.

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. 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. AC coupled single-wire interface. All PR pins are connected to a single communication bus through .001µF (500V) capacitors. This interface supports current sharing and is fault tolerant except for the communication bus.
