DFC10 SERIES
DUAL OUTPUT
DESCRIPTION The dual output DFC10 Series provides power solutions to meet commercial and industrial requirements. With power densities above 11 watts per cubic inch (0.67 watts per cm3), overcurrent protection, and five sided shielded case, the DFC10 meets rigorous needs in an industry standard case size. The 120KHz operating frequency of the DFC10 Series allows an increased power density 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. FEATURES * High Power Density, up to 11 Watts per Cubic Inch * Efficiencies to 79% * Fully Isolated, Fully Filtered Design * Greater than 700V Isolation * Overcurrent Protection * Five-Side Shielded Copper Case * Ultra Wide Range Input (4:1)

NOTES
(1) All parameters measured at Tc = 25C, nominal input voltage and full rated load unless otherwise noted. Refer to the Technical Reference Section for the definition of terms, measurement circuits and other information. Case is tied to the COMMON output pin. The functional temperature range is intended to give an additional data point for use in evaluating this power supply. At the low functional temperature the power supply will function with no side effects, however, sustained operation at the high functional temperature will reduce expected operational life. The data sheet specifications are not guaranteed beyond the case operating range. The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.

DFC10 SERIES - DUAL OUTPUT
NOTES
(1) All parameters measured at Tc = 25C, nominal input voltage and full rated load unless otherwise noted. Refer to the Technical Reference Section for the definition of terms, measurement circuits and other information. Noise is measured per 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 practices, output noise is measured with a 10f tantalum and 0.01F ceramic capacitor located 1 inch away from the converter. The converter may be safely operated at any load from zero to the full rating. Dynamic response of the converter may degrade if the converter is operated with less than 25% output load. Load regulation is defined for loading/unloading both outputs simultaneously. Load range is 25 to 100%. Cross regulation is defined for loading/unloading one output while the other output is kept at full load. Load range is 25 to 100%. Short term stability is specified after a 30 minute warmup at full load, constant line and recording the drift over a 24 hour period.
DFC10 SERIES APPLICATION NOTES: External Capacitance Requirements No external capacitance is required for operation of the DFC10 Series. If a capacitive input source is farther than 1" from the converter, an additional capacitor may be required at the input pins for proper operation. This input capacitor should have an ESR greater than 0.25 ohms. Input capacitors with an ESR less than 0.25 ohms may cause peaking of the input filter and actually degrade circuit performance. External output capacitance is not required for operation, however it is recommended that 1 F to 10 F of tantalum and 0.001 to 0.1 F ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400 F.
