Speci?cations are typical at +25 °C, Vin=nominal (+5V), Vout=nominal (+3.3V), full load, external caps and
natural convection unless otherwise indicated. Extended tests at full power must supply substantial forced
air?ow.
All models are tested and speci?ed with external 10μF ceramic output capacitors and a 22 μF external
input capacitor. All capacitors are low ESR types. These capacitors are necessary to accommodate our test
equipment and may not be required to achieve speci?ed performance in your applications. However, Murata
Power Solutions recommends installation of these capacitors. All models are stable and regulate within
spec under no-load conditions.
Input Back Ripple Current is tested and speci?ed over a 5 Hz to 20 MHz bandwidth. Input ?ltering is Cin=2 x
100 μF ceramic, Cbus=1000 μF electrolytic, Lbus=1 μH.
Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher
temperatures and/or lower air?ow, the DC/DC converter will tolerate brief full current outputs if the total
RMS current over time does not exceed the Derating curve.

setting.
