Eighth-brick
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 page 10).

BASIC OPERATION AND FEATURES
These converters use a digital controller for the buck stage and
boost stage (see Figure A). It automatically changes operating
mode (buck mode or boost) when the line voltage or output set
point changes. Both stages are accomplished with synchronous
rectifiers. Very high efficiency is maintained over wide input
and output ranges by shifting operational modes and use of
synchronous rectifiers.

To maintain the accuracy of the output voltage over load current,
it is vital that any trim-up resistor be terminated directly to the
converter’s Sense(-) pin (S option) or Vout(-) pin (C option), not
at the connection to the load. A separate Kelvin connection to the
PCB pad for the Vout(-) is optimal.

Input Under-Voltage Lockout: The converter is designed
to turn off when the input voltage is too low, helping avoid an
input system instability problem, described in more detail in the
applicationꢀ noteꢀ titledꢀ “Inputꢀ Systemꢀ Instability”.ꢀ ꢀ Theꢀ lockoutꢀ
circuitryꢀ isꢀ aꢀ comparatorꢀ withꢀ DCꢀ hysteresis.ꢀ ꢀ Whenꢀ theꢀ inputꢀ
voltage is rising, it must exceed the typical Turn-On Voltage
Threshold value (listed on the specification page) before the
converter will turn on. Once the converter is on, the input
voltage must fall below the typical Turn-Off Voltage Threshold
value before the converter will turn off.
The converter runs at a fixed frequency with a predictable
EMI performance.
This series of quarter-brick and eighth-brick converters use the
industry standard footprint and pin-out configuration.
CONTROL FEATURES
REMOTE ON/OFF: The ON/OFF input permits the user to con-
trol when the converter is on or off. Only Negative ON/OFF logic
is available in this power module series.
Output Current Shutdown: To provide protection in an
output short condition, the unit is equipped with internal short
circuitꢀ protection.ꢀ Whenꢀ theꢀ shortꢀ protectionꢀ isꢀ triggered,ꢀ theꢀ
unit shutdowns first. After approximately 16 ms inhibit time, the
units turn on again. If the short condition remains, the current
limit circuit will limit the output current. The units operate
normally once the fault condition is removed.
Negative logic ON/OFF signal turns the module OFF during logic
highꢀ(leaveꢀtheꢀpinꢀfloatingꢀorꢀsetꢀvoltageꢀbetweenꢀ1.8~3.3ꢀV)ꢀandꢀ
turns the module ON during logic low [tie to Vin(-)].
Internal Over-Voltage Protection: To fully protect from
excessive output voltage, the output over-voltage shutdown
circuitry is contained. This OVP is independent of the trimmed set
point. The shutdown point is fixed on the standard option.
OUTPUT VOLTAGE TRIM: The output voltage can be
programmed to any voltage between 0 V dc and Vmax by
connectingꢀoneꢀresistorꢀbetweenꢀtheꢀPinꢀ6ꢀ(TRIM)ꢀpinꢀandꢀPinꢀ5ꢀ
[Sense(-)]. For a desired output voltage, the value of the resistor
should be:
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 when the temperature at the sensed location reaches the
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.

Limited output voltage resolution: The internal voltage
control feedback loop has limited resolution. Therefore, the
output voltage will exhibit discrete steps as the loop responds
to changes in line, load, trim, or remote sense. For instance,
onꢀ closeꢀ examination,ꢀ theꢀ startupꢀ rampꢀ hasꢀ aꢀ “stair-step”ꢀ
shape. Likewise, a load transient response will be composed
of multiple discrete steps.

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 capacitance must be placed
directly adjacent to the input pin of the module, to minimize
input ripple voltage and ensure module stability.

Using this negative output setup impacts the available output
voltage range and current limit.
The output voltage range becomes 0 to Vmax - Vin, and the cur-
Output capacitance: For stable operation of the module, there
is no extra external capacitor required. To reduce the output
ripple and improve dynamic response to a step load change,
additional capacitance at the output can be used. Low ESR
polymer and ceramic capacitors are recommended to improve
the dynamic response of the module. In many applications,
however, additional external output capacitance is a requirement
which will cause the startup time to change.
