SPECIFICATIONS, CONTINUED
Murata Power Solutions recommends the specications below when installing these converters. These specications vary depending on the solder type.
Exceeding these specications may cause damage to the product. Your production environment may differ; therefore please thoroughly review these guidelines
with your process engineers.

SOLDERING GUIDELINES
(1) All models are tested and specied with external 1||10 μF ceramic/tantalum output capaci-
tors and no 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 specied
performance in your applications. All models are stable and regulate within spec under no-load
conditions.
General conditions for Specications are +25 deg.C, VIN = nominal, VOUT = nominal, full load.
Adequate airow must be supplied for extended testing under power.
(2) Input Ripple Current is tested and specied over a 5 Hz to 20 MHz bandwidth. Input ltering
is CIN = 33 μF, 100V tantalum, CBUS = 220 μF, 100V electrolytic, LBUS = 12 μH.
(3) Note that Maximum Power Derating curves indicate an average current at nominal input
voltage. At higher temperatures and/or lower airow, the DC/DC converter will tolerate brief
full current outputs if the total RMS current over time does not exceed the Derating curve. All
Derating curves are presented at sea level altitude. Be aware of reduced power dissipation
with increasing density altitude.
(4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case
3, ground xed conditions, Tpcboard=+25 deg.C, full output load, natural air convection.
(5) The On/Off Control is normally controlled by a switch. But it may also be driven with exter-
nal logic or by applying appropriate external voltages which are referenced to Input Common.
The On/Off Control Input should use either an open collector or open drain transistor.
(6) Short circuit shutdown begins when the output voltage degrades approximately 2% from
the selected setting.
(7) The outputs are not intended to sink appreciable reverse current. This may damage the
outputs.
(8) Output noise may be further reduced by adding an external lter. See I/O Filtering and Noise
Reduction.
(9) All models are fully operational and meet published specications, including “cold start” at
–40C.
(10) Regulation specications describe the deviation as the line input voltage or output load
current is varied from a nominal midpoint value to either extreme.
(11) Alternate pin length and/or other output voltages are available under special quantity order.
(12) Output overvoltage is non-latching. When the overvoltage fault is removed, the converter
will immediately recover.
(13) Do not exceed maximum power specications when adjusting the output trim.
(14) At zero output current, the output may contain low frequency components which exceed
the ripple specication. The output may be operated indenitely with no load.
(15) If reverse polarity is accidentally applied to the input, a body diode will become forward bi-
ased and will conduct considerable current. To ensure reverse input protection with full output
load, always connect an external input fuse in series with the +VIN input.
