Specifications are typical at +25 deg.C, Vin=nominal (+5V.), Vout=nominal (+3.3V), full load, external caps
and natural convection unless otherwise indicated. Extended tests at higher power must supply substantial
forced airflow.
All models are tested and specified with external 1 μF paralleled with 10 μF 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 specified 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 specified over a 5 Hz to 20 MHz bandwidth. Input filtering is
Cin=2 x 100 μF tantalum, 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 airflow, the DC/DC converter will tolerate brief full current outputs if the total
RMS current over time does not exceed the Derating curve.

-Input Common. A logic gate may also be used by applying appropriate external voltages which not exceed
+Vin.
Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected
setting.
“Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output.
If the overcurrent condition still exists, the restart current will be removed and then tried again. This short
current pulse prevents overheating and damaging the converter. Once the fault is removed, the converter
immediately recovers normal operation.
Output noise may be further reduced by adding an external filter. At zero output current, the output may
contain low frequency components which exceed the ripple specification. The output may be operated
indefinitely with no load.
