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 Naos Raptor 20A module should be connected to
a low-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 20A of load current with 2x22
µF or 4x22 µF ceramic capacitors and an input of 12V.

voltages with 2x22 µF or 4x22 µF ceramic capacitors

Output Filtering

The Naos Raptor 20A 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. For stable operation of the module, limit the
capacitance to less than the maximum output
capacitance as specified in the electrical specification
table. Optimal performance of the module can be
achieved by using the Tunable Loop
later in this data sheet.

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, CSA C22.2 No. 60950-1-03, and VDE
0850:2001-12 (EN60950-1) 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.

An input fuse for the module is recommended. Due to the
wide input voltage and output voltage ranges of the
module, different fuse ratings are recommended as
shown in Table 1. These are suggested “maximum” fuse
ratings. However, for optimum circuit protection, the fuse
value should not be any larger than required in the end
application. As an option to using a fuse, no fuse is
required, if the module is

1. powered by a power source with current limit
protection set point less than the protection
device value listed in Table 1, and

2. the module is evaluated in the end-use
equipment.

The Naos Raptor 20A modules feature an On/Off pin with
positive logic for remote On/Off operation. If not using the
On/Off pin, leave the pin open (the module will be ON,
except for the -49 option modules where leaving the pin
open will cause the module to remain OFF). The On/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.

To provide protection in a fault condition, these modules

unit will survive temperatures beyond its rating. Once the

Feature Descriptions (continued)

Power Good

The Naos Raptor 20A modules provide a Power Good
Status signal that indicates whether or not the power
module is functioning properly.

PwGood is a power good signal implemented with an
open-collector output to indicate that the output voltage is
within the regulation limits of the power module. The
PwGood signal will be de-asserted to a low state If any
condition such as over-temperature, over-current, or
over-voltage occurs which would result in the output
voltage going out of range.

Output Voltage Programming

The output voltage of the Naos Raptor 20A module can
be programmed to any voltage from 0.59Vdc to 6Vdc by
connecting a resistor between the Trim+ and Trim– 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. 48. 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 3.8V
and higher, the input voltage needs to be larger than the
minimum of 4.5V.

Without an external resistor between Trim+ and Trim–

Monotonic Start-up and Shutdown

The Naos Raptor 20A modules have monotonic start-up
and shutdown behavior for any combination of rated input
voltage, output current and operating temperature range.

Tunable Loop

The Naos Raptor 20A 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
tuned externally by connecting a series R-C between the
SENSE and TRIM pins of the module, as shown in Fig.

51. 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.

deviation limits for some common output voltages in the

Thermal Considerations

Power modules operate in a variety of thermal
environments; however sufficient cooling should always
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

52. The preferred airflow direction for the module is in

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 RoHS­compliant 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 technical representative for more details.
