DFA20 SERIES – SINGLE OUTPUT

NOTES

(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.

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

0.01μF ceramic in parallel with a 1μF/35V Tantalum capacitor located 1" away from the converter to

simulate your PCB’s standard decoupling. Input reflected ripple is measured into a 10μH source

impedance.

(2)

(3)

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.
