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 (VIN = 12Vdc). These
modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output
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 LoopTM, allows the user to
optimize the dynamic response of the converter to match the load.

with an input voltage of 12V. Table 3 shows the
recommended values of RTUNE and CTUNE for different
values of ceramic output capacitors up to 1000uF, again
for an input voltage of 12V. The value of RTUNE should
never be lower than the values shown in Tables 2 and
3. Please contact your Lineage Power technical
representative to obtain more details of this feature as
well as for guidelines on how to select the right value of
external R-C to tune the module for best transient
performance and stable operation for other output

Monotonic Start-up and Shutdown
The NQR010A0X4 10A modules have monotonic start-
up and shutdown behavior for any combination of rated
input voltage, output current and operating temperature
range.
Tunable LoopTM
The NQR010A0X4 10A modules have a new feature
that optimizes transient response of the module called
Tunable LoopTM. External capacitors are usually added
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 LoopTM feature allows the loop to
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.
