Description

The NQR010A0X4 SIP power modules are non-isolated dc-dc converters in an industry standard package that can
deliver up to 10A of output current with a full load efficiency of 94% at 5Vdc output voltage (V
modules operate over a wide range of input voltage (V
voltage from 0.59Vdc to 6Vdc, programmable via an external resistor. Features include remote On/Off, adjustable
output voltage, over current and over temperature protection. A new feature, the Tunable Loop
optimize the dynamic response of the converter to match the load.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.

Design Considerations

Input Filtering

The NQR010A0X4 10A module should be connected
to a low ac-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.

To minimize input voltage ripple, low-ESR ceramic or
polymer capacitors are recommended at the input of the
module. Figure 46 shows the input ripple voltage for
various output voltages at 10A of load current with 1x22
µF or 2x22 µF ceramic capacitors and an input of 12V.

voltages with 1x22 µF or 2x22 µF ceramic
capacitors at the input (10A load). Input voltage is
12V.

Output Filtering

The NQR010A0X4 10A modules are designed for low
output ripple voltage and will meet the maximum output
ripple specification with no external capacitors.
However, additional output filtering may be required by
the system designer for a number of reasons. First,
there may be a need to further reduce the output ripple
and noise of the module. Second, the dynamic
response characteristics may need to be customized to
a particular load step change.

To reduce the output ripple and improve the dynamic
response to a step load change, additional capacitance
at the output can be used. Low ESR ceramic and
polymer are recommended to improve the dynamic
response of the module. Figure 47 provides output
ripple information for different external capacitance
values at various Vo and for a load current of 10A. For
stable operation of the module, limit the capacitance to
less than the maximum output capacitance as specified
in the electrical specification table. Optimal

Safety Considerations

For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards,
i.e., UL 60950-1 2nd Edition, CSA C22.2 No. 60950-1­07, and VDE 0805-1+A11:2009-11 (DIN EN60950-1
2nd Edition) Licensed.

For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements. The power module
has extra-low voltage (ELV) outputs when all inputs are
ELV.

A 15A quick acting input fuse for the module is
required.

Feature Descriptions

Remote On/Off

The NQR010A0X4 10A power modules feature an
On/Off pin with positive logic for remote On/Off
operation. If the On/Off pin is not being used, leave the
pin open (the module will be ON). The On/Off signal
(V

) is referenced to ground. During a Logic High on

On/Off

the On/Off pin, the module remains ON. During Logic­Low, the module is turned OFF.

Overcurrent Protection

To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current limiting
continuously. At the point of current-limit inception, the
unit enters hiccup mode. The unit operates normally
once the output current is brought back into its specified
range. The average output current during hiccup is 10%

To provide protection in a fault condition, these modules

will shut down if the overtemperature threshold of 130ºC
is exceeded at the thermal reference point T

. The
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.

Output Voltage Programming

The output voltage of the NQR010A0X4 10A module
can be programmed to any voltage from 0.59dc to 6Vdc
by connecting a resistor between the Trim+ and GND
pins of the module. Certain restrictions apply on the
output voltage set point depending on the input voltage.
These are shown in the Output Voltage vs. Input
Voltage Set Point Area plot in Fig. 49. The Upper Limit
curve shows that for output voltages of 0.9V and lower,
the input voltage must be lower than the maximum of
14V. The Lower Limit curve shows that for output
voltages of 3.3V and higher, the input voltage needs to
be larger than the minimum of 4.5V.

Monotonic Start-up and Shutdown

The NQR010A0X4 10A modules have monotonic start­up and shutdown behavior for any combination of rated
input voltage, output current and operating temperature
range.

Tunable Loop

The NQR010A0X4 10A modules have a new feature
that optimizes transient response of the module called
Tunable Loop
to improve output voltage transient response due to
load current changes. Sensitive loads may also require
additional output capacitance to reduce output ripple
and noise. Adding external capacitance however
affects the voltage control loop of the module, typically
causing the loop to slow down with sluggish response.
Larger values of external capacitance could also cause
the module to become unstable.

To use the additional external capacitors in an optimal
manner, the Tunable Loop
be tuned externally by connecting a series R-C between
the VOUT and TRIM pins of the module, as shown in
Fig. 52. This R-C allows the user to externally adjust
the voltage loop feedback compensation of the module
to match the filter network connected to the output of
the module.

NQR010A0X4: Non-Isolated DC-DC Power Modules

Thermal Considerations

Power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.

Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel. The test set-up
is shown in Figure 53. The preferred airflow direction
for the module is in Figure 54.

Post solder Cleaning and Drying
Considerations

Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect both
the reliability of a power module and the testability of the
finished circuit-board assembly. For guidance on
appropriate soldering, cleaning and drying procedures,
refer to Board Mounted Power Modules: Soldering and
Cleaning Application Note.

Through-Hole Lead-Free Soldering
Information

These RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-compliant finish that is compatible
with both Pb and Pb-free wave soldering processes. A
maximum preheat rate of 3°C/s is suggested. The wave
preheat process should be such that the temperature of
the power module board is kept below 210°C. For Pb
solder, the recommended pot temperature is 260°C,
while the Pb-free solder pot is 270°C max. Not all
RoHS-compliant through-hole products can be
processed with paste-through-hole Pb or Pb-free reflow
process. If additional information is needed, please
consult with your Lineage Power representative for
more details.
