DC-DC Converter
The NiQor Half-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 Half-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. These modules are
RoHS 6/6 compliant (see page 13).

NiQor Half-brick module
Protection Features
Operational Features
• Input under-voltage lockout protects the converter at low input
voltage conditions
• Over-current shutdown protects converter from excessive
load current or short circuits
• Input/output over-voltage protection protects load and regulator
from damaging voltages
• Thermal shutdown protects converter from abnormal
• High efficiency, 96% at full rated load current
• Delivers up to 40A of output current
• Input Voltage Range: 9-60 Vdc
• Output Voltage Range: 0 - 60V (negative output is possible)
• Extensive on-board input and output filtering
• No minimum load requirement means no preload resistors required
• Adjustable current limit with current monitor
environmental conditions

BASIC OPERATION AND FEATURES
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
can be pulled low (to Vsense-) by an optocoupler, an open-
source/drain transistor or wired permanently to Vsense-.
To provide noise immunity the input has 0.3V of hysteresis.
The converter runs at a fixed frequency with a predictable
EMI performance.
This half-brick converter uses the industry standard footprint
and pin-out configuration. A typical V-I characteristic, with
Vsetpoint=50V and Isetpoint=28A, when operating from
Vin=30V, is shown in Figure A.
Multiple units that have a common Vsense- connection
can be controlled by the same On/Off signal, but it is
recommended that a small schottky diode be added to each
input as shown in Figure B.

CLOCK SYNCHRONIZATION: The module will
synchronize its switching to a clock signal at the SyncIn pin
(relative to Vsense-) of between 200 and 300KHz. For noise
immunity, the input has 0.1V hysteresis. It can be driven
by any standard logic gate. The input has an internal 5KΩ
pull-up to 3.3V; if unused, leave this input floating or tie it
directly to Vsense-.
OUTPUT VOLTAGE SETPOINT: The output voltage can
be programmed to any voltage between 0 V dc and Vmax
by connecting one resistor between the Vset pin (6) and
Vsense- (5); See Figure C. For a desired output voltage, the
value of the resistor should be:
11830 x Vmax

-10912

InputUnder-VoltageLockout: Theconverterisdesigned
to turn off when the input voltage is too low, helping avoid
an input system instability problem, described in more detail
in the application note titled “Input System Instability”. 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 (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.

Alternatively, the Vset pin can be driven from an external
voltage source: Undriven, this pin floats at 2.5V which
sets the output to 0V. See Figure 10 for the large scale
dynamics of this input.
Output Current Shutdown: To provide protection in an
output short condition, the unit is equipped with internal
short circuit protection. When the short-circuit protection
is triggered, the converter shuts down and then waits an
inhibit time (~16ms), after which it tries to turn on again. If
the short condition remains, the current limit circuit will limit
the output current. The unit will return to normal operation
once the fault condition is removed.

Vvset(Vset) = 2.366 – 2.316
(Vmax )
See Figure 9
where:
Vset = desired output voltage setpoint
Internal Over-Voltage Protection: To fully protect from
excessive output voltage, the unit contains an output over-
voltage shutdown that is fixed at ~110% of Vmax. If this
limit is reached, the converter shuts down and then waits
an inhibit time (~16ms), after which it restsarts.
Vmax = maximum rated output voltage (60V)
OUTPUT CURRENT SETPOINT: The maximum output
current (effectively the current limit) can be reduced to
any value between 0 and Imax by connecting one resistor
between the Iset pin (B) and Vsense- (5); see Figure C.
The value of the resistor should be:
Over-Temperature Shutdown: Two sensors in the
module monitor the temperature of both the buck and boost
sections. When the temperature at either sensor exceeds
the Over Temperature Shutdown value, the converter is
disabled. It will restart normally when it then cools by the
amount of the Over-Temperature Shutdown Hysteresis.

where:
Iset = desired output current setpoint
Imax = maximum rated output current (40A)
Undriven, the Iset pin floats to 2.5V which sets the current
limit at its nominal value of 115%*Imax. See Figure 12 for
the large signal dynamics of this control.

APPLICATION CONSIDERATIONS
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 whitepaper on Input System Stability for guidance

Figure D: Negative output setup
Output capacitance: An output capacitor of at least
100uF with an ESR of ~50mOhms is recommended to damp
the resonance of the output filter. More capacitance can be
added to improve dynamic response to load variation; there
is not 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.
Note that all control signals are referenced to Vsense-,
which in this arrangement is at Vout- potential.
