DC-DC Converter
The NiQor® eighth-brick dc-dc converter is a non-isolated
buck-boost regulator, which employs synchronous rectification
to achieve extremely high conversion efficiency. The High
Input Voltage NiQor Brick family of converters can be used
in traditional DPA (distributed power architecture) systems or
provide a regulated output voltage from a battery source or
other variable voltage source. The NiQor Brick family can be
configured to Buck the input voltage down to a lower voltage
or Boost the input voltage up to a higher voltage using a
single external resistor. The module is RoHS 6/6 compliant
(see last page).

CONTROL FEATURES
This converter consists of integrated buck and boost
converters, both controlled simultaneously by a digital
controller. It automatically changes operating mode (buck
mode or boost) when the line voltage or output set point
changes. Very high efficiency is maintained over wide input
and output ranges by shifting operational modes and use of
synchronous rectifiers.
REMOTE ON/OFF: Only Negative On/Off logic is available
in the converter series: logic high at the input turns the
converter Off while a logic low turns in On. Timing of this
is shown in Figures 7, 8. A high level can be driven to any
voltage between 1.5V and 3.3V, or simply left floating as
the unit contains an internal 10KΩ pull-up to 3.3V. The pin

OUTPUT VOLTAGE SETPOINT: The output voltage can
be programmed to any voltage between 0 V dc and Vmax
by connecting one resistor between the Pin 6 (Vset) and
Pin 5 [Vsense(-)](S-Version) or Pin 4 [-Vout](C-version);
See Figure C. For a desired output voltage, the value of the
resistor should be:
Rvset(Vset) =
[(
11830 x Vmax

)

(Ω)
NOTE: To maintain the accuracy of the output voltage over
load current, it is vital that the trim resistor be connected to
the convertor's Vsense(-) pin (for the S-option) or -Vout pin
(for the C-option), locally at the convertor, not at a remote
location nearer to the load. A separate Kelvin connection to
the PCB pad for the -Vout is optimal for the C-option.

Input filtering: These modules should be connected to a
low-impedance source. A highly inductive source can affect
the stability of the module. An input capacitor must be placed
adjacent to the input pins of the module to minimize input
ripple voltage and ensure stability. See SynQor's application
note titled Input System Stability for guidance on selecting
appropriate input filter elements.

added to improve dynamic response to load variation; there
is no upper limit on the value of the output capacitance.
Very large output capacitors may slow the converter's start
up time due to the current required to charge them being
limited by current limit or Isetpoint.

Remote sense (S-option only): In the event of an open
sense line, the module maintains output voltage regulation
via internal resistors between its Vsense+ and +Vout, and
Vsense- and -Vout pins. To avoid damaging those resistors,
maintain the voltage differentials to within the limits in
ABSOLUTE MAXIMUM RATINGS at all times.
Current limit: Available current is limited by output current
