Datasheet

These are partial model numbers. Please refer to the full model number struc-
ture for complete ordering part numbers.
Min. Iout = 3 Amps for UVQ-3.3 Vout models.
All specications are at nominal line voltage and full load, +25°C unless other-
wise noted. See detailed specifications.
Output capacitors are 1uF ceramic || 10 uF electrolytic. Input cap is 22 uF, low
ESR, except UVQ-24/4.5 is 33uF and UVQ-48/2.5 uses no input cap. I/O caps are
necessary for our test equipment and may not be needed for your application.
Iout = 14 Amps max. with Vin = 18-19.5 Volts.
UVQ Pin 9 Baseplate Connection
The UVQ series may include an optional installed baseplate for extended
thermal management. Various UVQ models (see list below) are also available
with an additional pin 9 on special order which connects to the baseplate but is
electrically isolated from the rest of the converter. Please refer to the mechani-
cal drawings.
Pin 9 offers a positive method of controlling the electrical potential of the
baseplate, independent of the converter. Some baseplate models cannot
include pin 9 and in such cases, the baseplate is grounded by the mounting
bolts. Or consider adding an external lugged washer with a grounding terminal.
The baseplate may be ordered by adding a “B” to the model number tree
and pin 9 will be pre-installed by adding a “9”. The two options are separate.
Please refer to the Ordering Guide. Do not order pin 9 without the baseplate.
Note that “pin 9” converters may be on limited forecast, requiring minimum
order quantities and scheduled deliveries.
Models available with Pin 9:
UVQ-12/10-D48
UVQ-1.5/40-D24
Models which are NOT available with Pin 9:
UVQ-5/20-D24 and –D48
UVQ-3.3/30-D24
UVQ-3.3/35-D48
UVQ-2.5/35-D24
UVQ-2.5/40-D48
Other models which are not listed will be reviewed for future pin 9 accomo-
dation.
