

Monotonic startup into normal and pre-biased

loads

Units are offered with a ﬁ xed output voltage and

current up to 45 Amps. UEEs operate over a wide

temperature range (up to +85 degrees Celsius at

moderate airﬂ ow) with full rated power. Synchro-

nous rectiﬁ er topology yields excellent efﬁ ciency.

UEEs achieve these impressive mechanical and

environmental specs while delivering excellent

electrical performance in an industry standard

DOSA compatible through-hole package or surface

mount option. The unit is fully protected against

input undervoltage, output overcurrent and short

circuit. An on-board temperature sensor shuts

down the converter if thermal limits are reached

and automatically restarts the converter when the

fault is removed.

An On/Off control input enables phased startup

and shutdown in multi-voltage applications. UEEs

include a Sense input to correct for ohmic losses. A

trim input may be connected to a user’s adjustment

potentiometer or trim resistors for output voltage

calibration.

UEEs include industry-standard safety certiﬁ -

cations and BASIC I/O insulation provides input/

output isolation to 2250V. Radiation and conducted

emission testing is performed to widely accepted

EMC standards.

UEE 150W Series Isolated, High-Density, Eighth-Brick DOSA Low Proﬁle DC-DC Converters TECHNICAL NOTES THROUGH-HOLE SOLDERING GUIDELINES Murata Power Solutions recommends the speciﬁcations below when installing these converters. These speciﬁcations vary depending on the solder type. Exceeding these speciﬁcations may cause damage to the product. Your production environment may differ; therefore please thoroughly review these guidelines with your process engineers.
PAGE 31
UEE 150W Series Isolated, High-Density, Eighth-Brick DOSA Low Proﬁle DC-DC Converters Input Source Impedance These converters will operate to speciﬁcations without external components, assuming that the source voltage has very low impedance and reasonable input voltage regulation. Since real-world voltage sources have ﬁnite impedance, performance is improved by adding external ﬁlter components. Sometimes only a small ceramic capacitor is sufﬁcient.
PAGE 32
UEE 150W Series Isolated, High-Density, Eighth-Brick DOSA Low Proﬁle DC-DC Converters Note that the temperatures are of the ambient airﬂow, not the converter itself which is obviously running at higher temperature than the outside air. Also note that very low ﬂow rates (below about 25 LFM) are similar to “natural convection,” that is, not using fan-forced airﬂow. Murata Power Solutions makes Characterization measurements in a closed cycle wind tunnel with calibrated airﬂow.
PAGE 33
UEE 150W Series Isolated, High-Density, Eighth-Brick DOSA Low Proﬁle DC-DC Converters Please observe Sense inputs tolerance to avoid improper operation: [Vout(+) −Vout(-)] − [Sense(+) −Sense(-)] ≤ 10% of Vout Output overvoltage protection is monitored at the output voltage pin, not the Sense pin. Therefore excessive voltage differences between Vout and Sense together with trim adjustment of the output can cause the overvoltage protection circuit to activate and shut down the output.
