- Low noise ZCS/ZVS architecture Typical Applications:telecommunications and distributed power systems 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-to- out 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. * Part Numbering For pin styles see page 6. Slotted baseplate (style 1) requires no designator. For threaded baseplate add a “2” to the end of the part number. For thru-hole, add a “3”. See page 7 for dimensions. See part numbering chart on this page for other product grades.

ELECTRICAL CHARACTERISTICS
Electrical characteristics apply over the full operating range of input voltage, output load (resistive) and baseplate temperature, unless otherwise specified. All temperatures refer to the operating temperature at the center of the baseplate. Baseplate Slotted (Style 1) Slotted baseplate (style 1) requires no designator. For threaded baseplate add a "2" to the end of the part number. For thru-hole add a "3". Pin style Short (Style 1) For long pin configuration add “L ” to the end of the part number.See page 7 for pin dimensions.

See Figures 7 and 8. CONTROL FUNCTIONS - SC PIN Figure 8—Output voltage trim up circuit.Figure 7—Output voltage trim down circuit. R D (ohms) = 1,000 Vout Vnom - Vout +Out SC –Out R U Trim Up LoadError Amp 1kΩ 1.23V 0.033µF Load +Out SC –Out R D Trim Down Error Amp 1kΩ 1.23V 0.033µF Trim Down 1. This converter is nota 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 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 activated. R U (ohms) = 1,000 (Vout-1.23) Vnom –1,000 1.23 (Vout-Vnom) 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.
