Specification Notes:
() All models are tested and specified with 300 lfm airflow, external || 0F ceramic/tantalum
output capacitors and a 00F 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 specified performance in your applications. All models are stable and regulate within
spec under no-load conditions.
General conditions for Specifications are +25°C, VIN = nominal, VOUT = nominal, full load unless
noted.
(2) Input Ripple Current is tested and specified over a 5Hz to 20MHz bandwidth. Input filtering is
CIN = 33F tantalum, CBUS = 220F electrolytic, LBUS = 2H.
(3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage.
At higher temperatures and/or lower airflow, 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 increas-
ing density altitude.
(4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method , Case 3,
ground fixed conditions, Tpcboard = +25°C, full output load, natural air convection.
(5) The On/Off Control may be driven with external logic or by applying appropriate external voltages
which are referenced to Input Common. The On/Off Control Input should use either an open
collector/open drain transistor or logic gate.
(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. Sinking excessive reverse
current may damage the outputs.
(8) Output noise may be further reduced by adding an external filter. See I/O Filtering and Noise
Reduction.
(9) All models are fully operational and meet published specifications, including “cold start” at –40°C.
(0) Regulation specifications describe the deviation as the line input voltage or output load current is
varied from a nominal midpoint value to either extreme.
() Alternate pin length and/or other output voltages are available under special quantity order.
(2) Overvoltage shutdown on 48V input models can be eliminated under special quantity order. OV
shutdown can be deleted in order to comply with certain telecom reliability requirements. These
requirements attempt continued operation despite significant input overvoltage.
(3) Do not exceed maximum power specifications when adjusting the output trim.
(4) Note that the converter may operate up to +05°C with the baseplate installed (+00°C for the
UQQ-3.3/25-Q48). However, thermal self-protection occurs near +20°C Therefore, +05°C is
recommended to avoid thermal shutdown.
(5) If reverse polarity is accidentally applied to the input, a body diode will become forward biased
and will accept considerable current. To ensure reverse input protection, always connect an
external input fuse in series with the +VIN input. Use approximately twice the full input current
rating with nominal input voltage.
(6) For On/Off Control on negative-polarity UQQ-3.3/25-Q48N models, the maximum OFF mode
control voltage is +3.5 Volts. For the ON mode, the range is pin grounded to + Volt max.
