To increase the output voltage, the user should connect a
resistorbetweenPin6(TRIM)andPin7(SENSE(+)input).For
a desired increase of the nominal output voltage, the value of
the resistor should be

Rtrim-up and Rtrim-down, showing the total range the output
voltage can be trimmed up or down.

due to both trimming and remote load voltage drops, should not

PROTECTIONFEATURES
Input Under-Voltage Lockout: The converter is designed
to turn off when the input voltage is too low, helping to avoid
an input system instability problem, which is described in more
detail in the application note titled “Input System Instability”
on the SynQor website. The lockout circuitry is a comparator
with DC hysteresis. When the input voltage is rising, it must
exceed the typical “Turn-On Voltage Threshold” value* before
theconverterwillturnon.Oncetheconverterison,theinput
voltagemustfallbelowthetypicalTurn-OffVoltageThreshold
value before the converter will turn off.
Output Current Limit:Iftheoutputcurrentexceedsthe“Output
DCCurrentLimitInception”point*,thenafastlinearcurrentlimit
controller will reduce the output voltage to maintain a constant
output current. If as a result, the output voltage falls below the
“Output DC Current Limit Shutdown Voltage”* for more than
50ms, then the unit will enter into hiccup mode, with a 500ms
off-time. The unit will then automatically attempt to restart.
Back-Drive Current Limit:Ifthereisnegativeoutputcurrent
of a magnitude larger than the “Back-Drive Current Limit while
Enabled”specification*,thenafastback-drivelimitcontrollerwill
increase the output voltage to maintain a constant output current.

Over-Temperature Shutdown: A temperature sensor on the
converter senses the average temperature of the module. The
thermal shutdown circuit is designed to turn the converter off
whenthetemperatureatthesensedlocationreachesthe“Over-
Temperature Shutdown” value*. It will allow the converter to
turn on again when the temperature of the sensed location falls
by the amount of the “Over-Temperature Shutdown Restart
Hysteresis”value*.
