DFC10 SERIES DUAL OUTPUT FEATURES DESCRIPTION High Power Density, up to 11 Watts per Cubic Inch The dual output DFC10 Series provides power solutions to meet Efficiencies to 79% commercial and industrial requirements. With power densities 3 Fully Isolated, Fully Filtered Design above 11 watts per cubic inch (0.67 watts per cm ), overcurrent Greater than 700V Isolation protection, and five sided shielded case, the DFC10 meets rigorous Overcurrent Protection needs in an industry standard case size. The 120KHz operating Five-Side Shielded Copper Case frequency of the DFC10 Series allows an increased power density Ultra Wide Range Input (4:1) while including adequate heat sinking and input/output filtering. This eliminates the need for external components in most applications. Full overload protection is provided by pulse-by-pulse current limiting on models with 48V input.

Refer to the DC/DC Technical Reference Section for the definition of terms, measurement External Capacitance Requirements circuits and other information. No external capacitance is required for operation of the DFC10 (2) Noise is measured per DC/DC Technical Reference Section. Measurement bandwidth is 0-20 MHz. RMS noise is measured over a 0.01-1 MHz bandwidth. To simulate standard PCB decoupling Series. If a capacitive input source is farther than 1 from the practices, output noise is measured with a 10f tantalum and 0.01F ceramic capacitor located 1 inch converter, an additional capacitor may be required at the input away from the converter.

Input capacitors with an ESR less (4) Load regulation is defined for loading/unloading both outputs simultaneously. Load range is 25 to than 0.25 ohms may cause peaking of the input filter and actually 100%.

(6) Short term stability is specified after a 30 minute warmup at full load, constant line and External output capacitance is not required for operation, however recording the drift over a 24 hour period. it is recommended that 1mF to 10mF of tantalum and 0.001 to 0.1mF ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400mF. 37
