M Typical at TA = +25°C under nominal line voltage and full-load conditions. All models are
N Ripple/Noise (R/N) measured over a 20MHz bandwidth.
O Devices have no minimum-load requirements and will regulate under no-load conditions.
Pin 9 Baseplate Connection
The UQQ series may include an optional installed baseplate for extended
thermal management. This baseplate is electrically isolated from the rest of the
converter. Various UQQ models are also available with an additional pin 9 on
special quantity order which electrically connects to the baseplate. Pin 9 is also
isolated from the rest of the converter. Please refer to the mechanical drawings.
Pin 9 offers a positive method of controlling the electrical potential of the base-
plate, independent of the converter. If you do not include pin 9, the baseplate
may also be grounded by the mounting bolts.

PERFORMANCE SPECIFICATIONS AND ORDERING GUIDE
specified with an external 1μF multi-layer ceramic and 10μF capacitors across their output pins
and 100μF external input capacitor.
Regulation specifications describe the output voltage deviation as the line voltage or load is
varied from its nominal/midpoint value to either extreme. (Load step = 50%.)

Load
Blank = No pin 9, standard
9 = Pin 9 installed, connects to baseplate
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.
Please see page 9 for heatsink information.
