DFC10E12S12

® DFC10 SERIES SINGLE OUTPUT DESCRIPTION The DFC10 Series provides power converter 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 the most rigorous needs in an industry standard case size. The 220KHz 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.

Refer to the DC/DC Technical Reference Section for the definition of terms, measurement circuits and other information. (2) The Case is tied to the -Input pin. (3) 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. (4) The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated. °C °C °C ° C/Watt General Chassis Mounting Kit 12V, 24V 4 2 Mechanical tolerances unless otherwise noted: X.XX dimensions: ±0.020 inches X.XXX dimensions: ±0.005 inches General Specifications (1) Isolation (2) Isolation Voltage Input to Output 12V, 24V Input to Output 48V 10 µA Leakage Input to Output Capacitance Enviromental Case Operating Range, Tc No Derating 1 0.42 (10.67) 18 18 18 18 36 36 36 36 72 72 72 72 0.000 0.100 (2.54) 0.200 (5.08) 0.500 (12.70) 0.61 (15.5) 0.000 9 9 9 9 18 18 18 18 36 36 36 36 3 0.3 (7.62) Max 0.300 (7.62) 0.800 (20.32) DFC10E12S3.3 DFC10E12S5 DFC10E12S12 DFC10E12S15 DFC10E24S3.3 DFC10E24S5 DFC10E24S12 DFC10E24S15 DFC10E48S3.3 DFC10E48S5 DFC10E48S12 DFC10E48S15 Min Output mA 0.000 Model Output VDC 0.61 (15.5) Input Range VDC (4) SIDE VIEW 0.040 (1.02) DIA TYP 14 (800) 678-9445 • FAX: (805) 388-0476 DFC10 SERIES – SINGLE OUTPUT Input Parameters (1) DFC10E12S3.3 Model Reflected Ripple (2) Input Current Full Load No Load Efficiency Switching Frequency Maximum Input Overvoltage, 100ms Maximum Turn-on Time, 1% Output Error TYP TYP TYP TYP TYP TYP Input Current Full Load No Load Efficiency Switching Frequency Maximum Input Overvoltage, 100ms Maximum DFC10E12S12 1070 7 78 440 145 1100 12 82 DFC10E24S3.3 DFC10E24S5 Units 210 70 500 7 83 mAPP mArms 1060 15 83 140 45 344 7 80 24 45 TYP DFC10E24S15 DFC10E48S3.3 210 70 530 10 85 510 10 86 % kHz ms DFC10E48S5 DFC10E48S12 260 6 81 150 50 270 6 83 100 35 176 6 78 DFC10E48S15 45 Units mAPP mArms 260 6 84 220 MAX mA VDC 10 DFC10E24S12 TYP TYP TYP TYP TYP TYP DFC10E12S15 220 MAX Model Reflected Ripple (2) 280 90 724 7 76 DFC10E12S5 85 mA % kHz VDC Output Parameters (1) Model Output Voltage DFC10E12S3.3 DFC10E24S3.3 DFC10E48S3.3 3.33 3.30 3.33 3.36 0.0 2.0 0.1 0.4 0.5 1.0 DFC10E12S5 DFC10E24S5 DFC10E48S5 5 4.95 5.00 5.05 0.0 2.0 0.1 0.4 0.01 0.2 DFC10E12S12 DFC10E24S12 DFC10E48S12 12 11.90 12.00 12.10 0.0 0.9 0.2 0.4 0.2 0.8 < 0.05 DFC10E12S15 DFC10E24S15 DFC10E48S15 15 14.90 15.00 15.10 0.0 0.7 0.2 0.4 0.2 0.8 Units VDC Load Regulation 25% Max Load - Max Load Line Regulation Vin = Min-Max VDC Short Term Stability (3) MIN TYP MAX MIN MAX TYP MAX TYP MAX TYP Long Term Stability TYP < 0.1 Input Ripple Rejection (4) TYP > 40 dB Noise, Peak - Peak (2) TYP 60 mVPP RMS Noise TYP TYP MAX 6 50 150 Output Voltage Accuracy Rated Load Range Temperature Coefficient Short Circuit Protection from +OUT to -OUT (2) (3) (4) A % % %/24Hrs %/kHrs A mVrms ppm/°C Continuous, Current Limit Protection NOTES (1) VDC 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. All parameters measured at Tc = 25°C, nominal input voltage and full rated load unless otherwise noted. Refer to the DC/DC Technical Reference Section for the definition of terms, measurement circuits and other information. Noise is measured per DC/DC 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 0.01µF / 100V ceramic capacitor in parallel with a 1µf / 35V Tantalum capacitor, 1 inch from the output pins to simulate standard PCB decoupling capacitance. Short term stability is specified after a 30 minute warmup at full load, constant line and recording the drift over a 24 hour period. The input ripple rejection is specified for DC to 120 Hz ripple with a modulation amplitude of 1% of Vin. External output capacitance is not required for operation, however 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. 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 Negative Outputs A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting -OUT as the negative output. 15 ® DFC10 SERIES – SINGLE OUTPUT OUTPUT POWER DERATING DFC10 SERIES BLOCK DIAGRAM ISOLATION TRANSFORMER 10 3 + OUTPUT 8 + INPUT 1 – INPUT 2 LOW NOISE FILTER 5 CURRENT MODE PWM POWER OUTPUT + - OUTPUT + 6 4 – ISO AMP 2 LOW TC BANDGAP REFERENCE SHIELDED COPPER CASE 0 50 60 70 80 90 AMBIENT TEMPERATURE 100 Typical Performance: (Tc=25°C, Vin=Nom VDC, Rated Load) Data for 12 Volt Input Models 12 VOLT INPUT CURRENT Vs.
