DFC15 SERIES SINGLE OUTPUT DESCRIPTION The DFC15 Series of DC/DC converters are designed to provide a wide range of PCB power solutions. The converter features dual output filters for low noise. Trim and remote ON/OFF features give flexibility to designs. The output of the converter is electrically isolated, thereby allowing the output to be configured as a positive or negative output voltage. The ultra-wide input range, from 20 to 60 volts, allows use in many industrial and communication applic.

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 1µF/35V tantalum capacitor located 1 inch away from the converter. Minimum load required for rated regulation only. Dynamic response may degrade if run at less than 25% full load. Short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. The input ripple rejection is specified for DC to 120Hz ripple with a modulation amplitude of 1% Vin.

However, for maximum performance, it is recommended that the DFC15 Series use a capacitor of sufficient ripple current capacity connected across the input pins if a capacitive input source is farther than 1” from the converter. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.05 Ohms from DC to 200KHz is required. External output capacitance is no.
