DESCRIPTION

Designed for digital, ECL, and analog application, the DFC6 Series will provide up to 6 watts in an industry standard package. Ultra-wide range input voltage allows operation from battery power as well as system power. The output is electrically isolated, thereby allowing the output to be configured as a positive or negative output voltage. Fully isolated and filtered outputs permit usage in sensitive and low noise circuits. The 100KHz operating frequency of the DFC6 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.

4 PLACES

(1) All parameters measured at Tc=25°C, 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. (2) 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. (3) The case Thermal Impedance is specified as the case temperature rise over ambient per package dissipated. (4) Reduced output power available with 3.5V input. Full power is available above 4.6V input. See input voltage derating curve for more information DFC6 SERIES SINGLE OUTPUT Rev. 04/2000

(1) All parameters measured at Tc=25°C, 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. (2) Reduced output power available at 3.5V input. Full output power is available above 4.6V input. See input voltage derating curve for more information. (3) Noise is measured per Technical Reference Section. Measurement bandwidth is 0-20 MHz for peak-peak measurements, 10 kHz to 1 MHz for RMS measurements. Output noise is measured with a 1µF/35V Tantalum capacitor located 1" away from the converter to simulate PCB standard decoupling. (4) Short term stability is specified after a 30 minute warmup at full load, constant line and recording the drift over a 24 hour period. (5) No minimum load required for operation. Dynamic regulation may degrade when run with less than 5% load. DFC6 SERIES APPLICATION NOTES: External Capacitance Requirements No external capacitance is required for operation of the DFC6 Series. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.15 Ohms from DC to 200KHz is required. 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. External output capacitance is not DFC6 SERIES – SINGLE OUTPUT required for operation, however it is recommended that 1 /H9262F to 10/H9262F of tantalum and 0.001 to 0.1 /H9262F ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400 /H9262F. Output Power The available output power of the DFC6 Series is reduced when operating below 4.6 volts. See Input Voltage Derating curve. Below 4.6 volts the output power is linearly derated from 100% at 4.6 volts to 50% at 3.5 volts. Negative Outputs A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting -OUT as the negative output.
