of these conditions may adversely affect long-term reliability. Proper operation
under conditions other than those listed in the Performance/Functional Speci?-
cations is neither implied nor recommended.
SPECIFICATION NOTES
(1) All models are tested and speci?ed with external capacitors listed in the
table below. The external capacitors listed below are ONLY for establishing test
speci?cations. They are required for our test ?xtures and equipment. Your applica-
tion may not need them. The converter is stable with no external capacitors but
Murata Power Solutions strongly recommends external caps. All caps are low-ESR
types. Where two or more capacitors are listed, these are connected in parallel. All
caps should mount close to the DC/DC using short leads.
All speci?cations are typical unless noted. General conditions for Speci?ca-
tions are +25 deg.C, V IN =nominal, V OUT =nominal, full load. Adequate air?ow must
be supplied for extended testing under power.
(2) Input Ripple Current is tested and speci?ed over a 5 Hz to 20 MHz band-
width. Input ?ltering is C IN =33 μF, 100V tantalum, C BUS =220 μF, 100V electro-
lytic, L BUS =12 μH.
(3) 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. All Derating curves are presented at sea level
altitude. Be aware of reduced power dissipation with increasing density altitude.
(10) Regulation speci?cations describe the deviation as the line input voltage
or output load current is varied from a nominal midpoint value to either extreme.
(11) The output overvoltage protection is automatic recovery after fault
removal. The overvoltage may occur either from internal failure or from an
external forcing voltage as in a shared power system.
(12) Output current limit and short circuit protection is non-latching. When the
overcurrent fault is removed, the converter will immediately recover.
(13) Do not exceed maximum power speci?cations when adjusting the output
trim.
(14) At zero output current, the output may contain low frequency components
which exceed the ripple speci?cation. The output may be operated inde?nitely
with no load.
(15) If reverse polarity is accidentally applied to the input, to ensure reverse in-
put protection with full output load, always connect an external input fuse in series
with the +V IN input. Use approximately twice the full load input current rating at
minimum input voltage.
(16) “Hiccup” 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 over-
heating and damaging the converter. Once the fault is removed, the converter
immediately recovers normal operation.
(17) On model UEI15-050-Q48, if V IN <20V, output trim may only be adjusted
downwards from +5.0V (more negative).
(18) Typical values s hown. For minimum and maximum values see table below.

CAUTION: This product is not internally fused. To comply with safety
agency certi?cations and to avoid injury to personnel or equipment, the user
must connect an external fast-blow fuse to the input terminals. See fuse
information.
(19) All models require 10% of Imax minimum output load to meet speci?-
cations. However, they will not be damaged at zero output load.
