E C N E O R - T R (800) 678-9445 FAX: (805) 388-0476 SINGLE OUTPUT DFA6 SERIES DESCRIPTION FEATURES The DFA6 Series provides quick power conversion solutions to Up to 6 Watts Output Power analog and digital systems. Requires few external components. Overcurrent Protection The converters provide plug-and-play versatility. The series Efficiency to 83% features an input range of 3:1. The output is electrically isolated, Low Input to Output Capacitance thereby allowing the output to be configured for positive or 700V Isolation, Input to Output negative output voltage. The DFA6 provides compact system Ultra-Wide Input Range (3:1) 2 power in less than 2.3 square inches (14.8 cm ). The DFA6 Series ultra-wide input and no load input current (7mA) makes it well suited for battery operation in commercial and industrial applications.

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 DFC6 Series. (2) 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 To meet the reflected ripple requirements of the converter, an input 1f / 35V Tantalum capacitor, 1 inch from the output pins to simulate standard PCB decoupling impedance of less than 0.35 Ohms from DC to 250KHz is required. capacitance. Reflected Ripple is measured with the appropriate input capacitor, and into a 10 H source impedance. See application notes for input capacitor requirements. If a capacitive input source is farther than 1 from the converter, an (3) Short term stability is specified after a 30 minute warmup at full load, constant line and recording the additional capacitor may be required at the input pins for proper drift over a 24 hour period. operation. External output capacitance is not required for operation, (4) The input ripple rejection is specified for DC to 120 Hz ripple with a modulation amplitude of 1% of Vin. 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. Negative Outputs A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting -OUT as the negative output. 12
