From an 9-36V or 18-75V input, UQQ’s deliver

outputs of 3.3V, 5V,12V,15V, or 24V. They employ

an interleaved, synchronous-rectiﬁ er topology that

exploits 100% of their duty cycle. They simultane-

ously achieve ultra-high efﬁ ciency, tight line/load

regulation, low noise, and quick step response.

A state of the art, single-board, open-frame

design with reduced component count, high

efﬁ ciency, low-on-resistance FET’s, and planar

magnetics embedded in heavy-copper pc boards

all contribute to impressive thermal derating.

The UQQ’s feature set includes high isolation,

input pi ﬁ lters, input undervoltage shutdown, output

overvoltage protection, current limiting, short-circuit

protection and thermal shutdown. The standard

footprint carries on/off control (positive or negative

polarity), output trim (+10/–20%) and output sense

functions.

All UQQ quarter-bricks are designed with full

magnetic and optical isolation up to 2250 Volts DC

(basic insulation).

For applications requiring wide range input, improved electrical and

thermal perfomance consider Murata Power Solutions’ new UQQ

Series “Quarter-Brick” DC-DC Converters. They measure just 1.45

x 2.22 x 0.43 inches (36.8 x 56.4 x 10.92mm) and ﬁ t the industry-

standard footprint.

UQQ Series Wide Input Range Single Output DC-DC Converters TECHNICAL NOTES 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 14
UQQ Series Wide Input Range Single Output DC-DC Converters Start-Up Threshold and Undervoltage Shutdown Under normal start-up conditions, the UQQ Series will not begin to regulate properly until the ramping input voltage exceeds the Start-Up Threshold. Once operating, devices will turn off when the applied voltage drops below the Undervoltage Shutdown point. Devices will remain off as long as the undervoltage condition continues.
PAGE 15
UQQ Series Wide Input Range Single Output DC-DC Converters Input Reverse-Polarity Protection If the input-voltage polarity is accidentally reversed, an internal diode will become forward biased and likely draw excessive current from the power source. If the source is not current limited or the circuit appropriately fused, it could cause permanent damage to the converter.

UQQ Series Wide Input Range Single Output DC-DC Converters UQQ Series Aluminum Heatsink Thermal Performance Please note – The UQQ series shares the same heatsink kits as the UVQ series. Therefore, when ordering these heat sinks, use the model numbers below which end with the ‘UVQ’ sufﬁx. The UQQ series converter baseplate can be attached either to an enclosure wall or a heatsink to remove heat from internal power dissipation. The discussion below concerns only the heatsink alternative.

UQQ Series Wide Input Range Single Output DC-DC Converters Calculating Maximum Power Dissipation Heat Sink Example To determine the maximum amount of internal power dissipation, ﬁnd the ambient temperature inside the enclosure and the airﬂow (in Linear Feet per Minute – LFM) at the converter. Determine the expected heat dissipation using the Efﬁciency curves and the converter Input Voltage.
