NOTES
(1)
All parameters measured at Tc=25°C, nominal input voltage and full rated load unless otherwise
noted.
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 warm-up at full load, constant line and recording
he drift over a 24 hour period.
Per ETSI-300-132
Recovery to within 1% in less than 1 millisecond after transient has been applied.

DFC25 SERIES APPLICATION NOTES:
External Capacitance Requirements
A low ESR external capacitance is required for operation of the DFC25 Series. For maximum
performance, it is recommended that the DFC25 Series use a capacitor of sufficient ripple current
capacity connected across the input pins, especially 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 0.09 Ohms at 200 kHz is required. External output capacitance is not required for
operation, however it is recommended that 1μF to 10μF of Tantalum and 0.001 to 0.1μF ceramic
capacitance be selected for each output to reduce system noise. Additional output capacitance may
be added for increased filtering, but should not exceed 400μF.
Remote ON/OFF Operation
The remote ON/OFF pin may be left floating if this function is not used. It is recommended to drive
this pin with TTL compatible circuitry. When the ON/OFF pin is pulled low with respect to the
-INPUT, the converter is placed in a low power drain state. The input capacitors are kept fully
charged in the OFF mode. For proper operation, this input may be driven from a logic gate directly.
The ON/OFF pin should never be pulled more than 0.3 volts below -INPUT or have a voltage
greater than +6 volts applied.
