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.

Certain applications and/or safety agencies may require the installation of
–SENSE
fuses at the inputs of power conversion components. Fuses should also be
used if the possibility of a sustained, non-current-limited, input-voltage polarity
–VIN
–VOUT
reversal exists. For MPS UQQ Series DC-DC Converters, fast-blow fuses are
recommended with values no greater than twice the maximum input current.
Trimming Output Voltage
Figure 5. Trim Connections To Increase Output Voltages Using Fixed Resistors
UQQ converters have a trim capability (pin 6) that enables users to adjust the
output voltage from +10% to –20% (refer to the trim equations). Adjustments
to the output voltage can be accomplished with a single ?xed resistor as shown
in Figures 5 and 6. A single ?xed resistor can increase or decrease the output
+VIN
+VOUT
+SENSE
voltage depending on its connection. Resistors should be located close to
the converter and have TCR’s less than 100ppm/°C to minimize sensitivity to

changes in temperature. If the trim function is not used, leave the trim pin open.
–SENSE
Standard UQQ’s have a "positive trim" where a single resistor connected from
the Trim pin (pin 6) to the +Sense (pin 7) will increase the output voltage. A
–VIN
–VOUT
resistor connected from the Trim Pin (pin 6) to the –Sense (pin 5) will decrease
the output voltage.
Figure 6. Trim Connections To Decrease Output Voltages Using Fixed Resistors
Trim adjustments greater than the speci?ed +10%/–20% can have an adverse
affect on the converter’s performance and are not recommended. Excessive
voltage differences between V OUT and Sense, in conjunction with trim adjust-
ment of the output voltage, can cause the overvoltage protection circuitry to

Temperature/power derating is based on maximum output current and voltage

at the converter’s output pins. Use of the trim and sense functions can cause
output voltages to increase, thereby increasing output power beyond the UQQ’s
UQQ-5/17-Q12, UQQ-5/20-Q48
speci?ed rating, or cause output voltages to climb into the output overvoltage
region. Therefore:

The Trim pin (pin 6) is a relatively high impedance node that can be susceptible

to noise pickup when connected to long conductors in noisy environments.
