Absolute maximums are stress ratings. Exposure of devices to greater than any of
any of these conditions may adversely affect long-term reliability. Proper operation
under conditions other than those listed in the Performance/Functional Specifi cations
Table is not implied nor recommended.
Adjustable Output 3 and 5-Amp DOSA-SMT PoLs
Specifi 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
airfl ow.
All models are tested and specifi ed with external 1 μF paralleled with 10μF ceramic/tantalum 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 specifi 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 specifi ed over a 5 Hz to 20 MHz bandwidth. Input fi ltering 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 airfl ow, the DC/DC converter will tolerate brief full current outputs if the total
RMS current over time does not exceed the Derating curve.
