a current into the converter’s SC/Trim pin to raise the output
voltage of the converter.
The current required to increase a converter’s output voltage
is dependent on the converter and its internal reference
circuitry. The QPO-1 is designed to drive a converter which
has a fixed reference voltage with a series resistor which can
be offset by the injection of current into the pin. The current
can be calculated using the following equation:
Where; VOUT = Nominal converter output voltage
VRPT = internal reference voltage
VHR = QPO-1’s headroom voltage.
RIN = internal series resistor.
The RSCSET resistor is calculated by dividing the headroom
voltage by ISCSET.
The RSCSET equation reduces to the
following:
Where; VOUT = Nominal converter output voltage
VRPT = internal reference voltage
RIN = internal series resistor.
When using one of Vicor’s Micro, Mini or Maxi converters, the
RIN = 1kΩ and the VRPT = 1.23V.
The RSL resistor, shown in Figure 3, is used to limit the
amount of current the QPO-1 can source during start-up. The
SC current is derived from the headroom voltage and at start-
up the headroom voltage is greater than when in normal
operation. This higher current can over-drive a converter to
the point where an over-voltage fault can occur. RSL is
calculated using the following equation:
Where; RSL = current limiting resistor for the QPO SC circuit,
VIN = the QPO’s input voltage,
VRPT = the nominal SC voltage of the converter,
ISCMAX = the current that will force a converter to
have 110% of its nominal voltage on its
output.
Where; ISCMAX = the current that will force a converter to
have 110% of its nominal voltage on its
output.
VSC = the nominal SC voltage of the converter,
RINT = the internal series resistor of the converter’s
reference circuit.
Remote Sense:
Compensation for the QPO-1’s voltage drop can be done
using the converter’s remote sense pins, if available. The on-
board sensing network can be attached as is shown in Figure
10, using RRS and CRS.
