DFC25 SERIES SINGLE OUTPUT DESCRIPTION The DFC25 Series DC/DC converter provides tightly regulated output voltages for industrial and datacom applications from 12, 24, or 48 Volt inputs. Available output power ranges from 24.75 to 30 watts. Excellent noise performance is attained via an aluminum case, toroidal magnetics, and double shielded transformers. Common mode and differential mode input filtering is integral to the design. Selected models provide 1544 volts isolation from the input to out.

DFC25 SERIES SINGLE OUTPUT DESCRIPTION The DFC25 Series DC/DC converter provides tightly regulated output voltages for industrial and datacom applications from 12, 24, or 48 Volt inputs. Available output power ranges from 24.75 to 30 watts. Excellent noise performance is attained via an aluminum case, toroidal magnetics, and double shielded transformers. Common mode and differential mode input filtering is integral to the design. Selected models provide 1544 volts isolation from the input to output. The input and output sections of the DFC25 Series are protected from overvoltage transients via internal circuitry. Same voltage models of the DFC25 family may be connected in parallel to achieve additional output current.

For maximum performance, it is recommended that the DFC25 Series use a capacitor of sufficient ripple current capacity connected across the input pins, especially if a capacitive input source is farther than 1" from the converter. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.09 Ohms at 200 kHz is required. External output capacitance is not required for operation, however it is recommended that 1µF to 10µF of Tantalum and 0.001 to 0.1µF ceramic capacitance be selected for each output to reduce system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400µF. Remote ON/OFF Operation The remote ON/OFF pin may be left floating if this function is not used. It is recommended to drive this pin with TTL compatible circuitry. When the ON/OFF pin is pulled low with respect to the -INPUT, the converter is placed in a low power drain state. The input capacitors are kept fully charged in the OFF mode. For proper operation, th.
