DC-DC Converter
The MCOTS 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 MCOTS
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 MCOTS 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.

BASIC OPERATION AND 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.
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.

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-.

CONTROL FEATURES
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 opensource/drain transistor or wired permanently to Vsense-.
To provide noise immunity the input has 0.3V of hysteresis.
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:
Rvset(Vset) =
[(
11830 x Vmax
Vset + 0.058 x Vmax
)
-10912
] (Ω)
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.

Alternatively, the Vset pin can be driven from an external

sets the output to 0V. See Figure 10 for the large scale
dynamics of this input.
PROTECTION FEATURES
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 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.
where:
Vset = desired output voltage setpoint
Vmax = maximum rated output voltage (60V)
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 (~100ms), 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.
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:
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 (~100ms), after which it restsarts.
Vvset(Vset) = 2.366 – 2.316
(

)

RIset(Iset) =
[(
0.0469 Imax + Iset

)
]
*10200 -10
(Ω)
Alternatively, the Iset pin can be driven from an external
voltage source:
Viset(Iset)=
where:
( 0.0953+2.085 * Iset/Imax )
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.
V
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
Cin2
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.
http://www.synqor.com/documents/appnotes/appnt_System_Instability.pdf
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.

Remote sense: 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.

output current in buck mode (Vin>Vout), and by maximum
input current in boost mode (Vin<Vout).

Figure E: Setup for output current sharing
Current Sharing: In applications requiring more power
than can be supplied from a single converter, multiple units
can be arranged to share the load as shown in Figure E.
The units should all be set at the same output voltage setpoint
by using identical Rvset resistors. In this arrangement, the
level of the Ishare/Imon bus is that of the average current
delivered by each converter.
