The NiQor® SMT DC/DC converter is a non-isolated
buck regulator, which employs synchronous rectification
to achieve extremely high conversion efficiency.
The
Non-Isolated
NiQor family of converters are used predominately in
DPA systems using a front end DC/DC high power brick
(48Vin to low voltage bus).
The non-isolated NiQor
converters are then used at the point of load to create the
low voltage outputs required by the design. The wide
trim module can be programmed to a variety of output
voltages through the use of a single external resistor.

BASIC OPERATION AND FEATURES
The NiQor series non-isolated converter uses a buck-converter
that keeps the output voltage constant over variations in line,
load, and temperature. The NiQor modules employ synchronous
rectification for very high efficiency.
For a desired increase of the nominal output voltage, the value of
the resistor should be:
Rtrim-up =
CONTROL FEATURES
REMOTE ON/OFF: The ON/OFF input permits the user to
control when the converter is on or off. There are currently two
options available for the ON/OFF input described in the table
below. Others may become available if demand exists.
1200
VDES - 0.8
_ 100 (W)
or
Dissipation throughout the converter is so low that it does not
require a heatsink or metal baseplate for operation. The NiQor
converter can thus be built more simply and reliably using high
yield surface mount techniques on a single PCB substrate.
The NiQor series of SIPs and SMT converters uses the established
industry standard footprint and pin-out configurations.

SMT
VOUT = 0.8+
where
1200
Rtrim-up + 100
(W)
VDES = Desired Output Voltage
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 ground foot, not at the connection to the load. A
separate Kelvin connection to the PCB pad for the ground foot
is optimal. Trim-down resistors should be terminated at the converter’s Sense+ pin.
We do not recommend bypassing the trim pin directly to ground
with a capacitor. The voltage gain from the trim pin to output
is rather large, 15:1. Ground bounce through a bypass capacitor could introduce significant noise to the converter’s control
circuit.
PROTECTION FEATURES
TRIM-UP: To increase the output voltage from the nominal
setpoint of 0.8V using an external resistor, connect the resistor
Rtrim-up between the TRIM and the Ground pin according to the
diagram below.
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.
Vout
Sense+
Output Current Limiting: To provide protection in an output
over load fault condition, the unit is equipped with internal overcurrent protection. When the over-current protection is triggered,
the unit enters hiccup mode. The units operate normally once the
fault condition is removed.
OUTPUT VOLTAGE TRIM: The TRIM input permits the user to
adjust the output voltage according to the trim range specifications by using an external resistor. If the TRIM feature is not being
used, leave the TRIM pin disconnected.

Phone 1-888-567-9596
Internal Over-Voltage Protection: To fully protect from
excessive output voltage, this series contains contains an Output
Over-Voltage Shutdown circuitry. This OVP is independent of
the trimmed setpoint. As such, the converter’s load is protected
from faults in the external trim circuitry (such as a trim pin shorted
to ground). Since the setpoint of this OVP does not track trim,
it is set at 6.0V. For more detailed information contact SynQor
technical support.

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.
APPLICATION CONSIDERATIONS
Input Filtering/Capacitance/Damping: The filter circuit of
Figure E is often added to the converter’s input to prevent switching noise from reaching the input voltage bus.
Figure H: Converter with Additional Output Capacitance
Active Load Sharing: For additional power requirements, the
SGA30 series of converters have a parallel feature available. To
implement forced load sharing, the following connections should
be made:
• The share pins of all units in parallel must be connected
together. The path of these connections should be as direct as
possible.
• All ON/OFF pins should be connected together.
Figure E: converter with Input Filter
In the SGA30 (surface mount) converters Cin = 20µF of high
quality ceramic capacitors. With Lin of 1µH, Cd should be
100-200µF and Rd should be 0.1-0.2W, in most applications.
For more information on designing the input filter and choosing
proper values, contact SynQor technical support.
Adding significant external pure ceramic capacitance directly
across the converter’s input pins is not recommended. Parasitic
inductance associated with the input pin geometry and PCB traces
can create a high-Q CLC circuit with any external capacitors. Just
a few nano-Henries of parasitic inductance can create a resonance
(or an overtone) near the converter’s switching frequency. To
avoid this high-frequency resonance, any external input filter
should exhibit a net source impedance of at least 20mW resistive
through this frequency range. This requirement is easily met with
the damping elements discussed above. Adding a small amount (a
few µF) of high-frequency external ceramic will not violate it.
If using converters at higher powers, consider the ripple current
rating of Cd. Contact SynQor technical support for details.
Output Capacitance: It is recommended to add at least 100µF
of capacitance, with an ESR in the 0.1W range, to the output of
the SGA30 series of converters. In many applications, however,
additional external output capacitance is required to reduce the
response to load transients to an allowable level.
For minimal overshoot upon recovery, Cd should be related to the
minimum in-circuit net ESR.
For more detailed derivations of these values contact SynQor
technical support.

The share bus is not designed for redundant operation and the
system will be non-functional upon failure of one of the units when
multiple units are in parallel. When not using the parallel feature,
leave the share pin open.
SURFACE MOUNT INFORMATION
PCB Layout Considerations: SynQor recommends that
the customer use a non-solder mask defined pad design. The
minimum recommended pad size is 0.074” x 0.122” (1.88mm
x 3.1mm) and the maximum pad size is 0.095” x 0.140”
(2.41mm x 3.56mm), see the mechanical diagram on page 2. Interconnection to internal power planes is typically required. This can be accomplished by placing a number of vias between
the SMT pad and the relevant plane. The number and location
of the vias should be determined based on electrical resistance,
current and thermal requirements. “Via-in-pad” design should be
avoided in the SMT pads. Solder mask should be used to eliminate solder wicking into the vias.
Pick and Place: The NiQor surface mount modules are
designed for automated assembly using standard SMT pick and
place equipment. The modules have a centrally located inductor
component with a flat surface area to be used for component
pick-up. The units use open frame construction and have a low
mass that is within the capability of standard pick and place
equipment. Those modules however have a larger mass than most
conventional SMT components and so variables such as nozzle
size, tip style, handling speed, and placement pressure should be
optimized for best results. A conformal tipped placement nozzle
design is recommended. Coplanarity of better than 0.004”
(0.1mm) is achieved through the SMT NiQor’s terminal design.

Reflow Soldering Guidelines: Figure J
shows a typical reflow profile for a eutectic
solder process. Due to variations in customer
applications, materials and processes, it is not
feasible for SynQor to recommend a specific
reflow profile. The customer should use this
profile as a guideline only. Since the NiQor surface mount modules have a larger thermal mass
and lower thermal resistance than standard SMT
components, it may be necessary to optimize
the solder reflow profile based on limitations of
the other components on the customer board.
Sufficient reflow time must be allowed to fuse the
plating on the connection to ensure a reliable
solder joint. The solder reflow profile should
be confirmed by accurately measuring the SMT
interconnect leads. Maximum case temperature
of 260°C (exposure for 5 seconds or less) is not
exceeded for the NiQor units.
Moisture Sensitivity: The NiQor surface
mount modules have an MSL rating 1 per IPC/
JEDEC J-STD-033A.

Cleaning and Drying: When possible, a no-clean solder
paste system should be used to solder the NiQor SMT units to
their application board. The modules are suitable for aqueous washing, however, the user must ensure sufficient drying
to remove all water from the converter before powering up.
Inadequate cleaning and drying can affect the reliability of the
converter and the testing of the final assembly.
