NOTES:
(1) All parameters measured at Tc = 25°C, nominal input voltage and full-rated load unless otherwise noted.
(2) Noise measurement bandwidth is 0-20 MHz for peak-to-peak measurements; 10 kHz to 1 MHz for RMS measurements. Output noise is
measured with a 0.01μF ceramic capacitor 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.
(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.
(4) The input ripple rejection is specified for DC to 120 Hz ripple with a modulation amplitude of 1% of Vin.
