Description

The Naos Raptor 40A SIP power modules are non-isolated dc-dc converters in an industry standard package that

can deliver up to 40A of output current with a full load efficiency of 92% at 3.3Vdc output voltage (VIN = 12Vdc).

These modules operate over a wide range of input voltage (VIN = 5Vdc-13.8Vdc) and provide a precisely regulated

output voltage from 0.6dc to 5.0Vdc, 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.

RoHS Compliant

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being

part of a complex power architecture. To preserve maximum flexibility, internal fusing is not included, however, to

achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-

acting fuse with a maximum rating of 30A (see Safety Considerations section). Based on the information provided in

this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be

used. Refer to the fuse manufacturer’s data sheet for further information.

Design Considerations

Input Filtering

The Naos Raptor 40A 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

capacitors are recommended at the input of the

module. Figure 40 shows the input ripple voltage for

various output voltages at 40A of load current with

1x22 µF or 2x22 µF ceramic capacitors and an input

of 12V.

voltages with 1x22 µF or 2x22 µF ceramic

Output Filtering

The Naos Raptor 40A 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 LoopTM feature described 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.

The input to these units is to be provided with a fast-

acting fuse with a maximum rating of 30A in the

positive input lead.

Feature Descriptions

Remote On/Off

The Naos Raptor 40A power modules feature a

remote On/Off capability with positive logic. If not

using the On/Off pin, leave the pin open (the module

will be ON. The On/Off signal (VOn/Off) is referenced to

ground.

During a Logic High on the On/Off pin, the module

remains ON. During Logic-Low, 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 typical average

output current during hiccup is 10% of Io,max.

Over Temperature Protection

To provide protection in a fault condition, the unit is

equipped with a thermal shutdown circuit. The unit will

shut down if the overtemperature threshold of 127ºC

is exceeded at the thermal reference point Tred. 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, module operation is disabled. The module will

begin to operate at an input voltage above the

undervoltage lockout turn-on threshold.

LINEAGE POWER 13

Power Good

The Naos Raptor 40A power 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-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 40A module

can be programmed to any voltage from 0.6Vdc to

5.0Vdc 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.

43. The Lower Limit curve shows that for output

voltages of 2.75V and higher, the input needs to be

larger than the minimum of 4.5V.

Without an external resistor between Trim + and Trim

calculate the value of the trim resistor, Rtrim for a

desired output voltage, use the following equation:

Rtrim is the external resistor in kΩ

Vo is the desired output voltage

Table 1 provides Rtrim values required for some

common output voltages.

By using a ±0.1% tolerance trim resistor with a TC of

±25ppm, a set point tolerance of ±0.8% can be

achieved as specified in the electrical specification.

The POL Programming Tool available at

www.lineagepower.com under the Design Tools

section, helps determine the required trim resistor

needed for a specific output voltage.

Note: Vin ≥ 180% of Vout at the module output pin.

Feature Descriptions (continued)

Tunable LoopTM

The Naos Raptor 40A 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 SENSE and TRIM pins of the module, as

shown in Fig. 44. 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.

Recommended values of RTUNE and CTUNE are given

in Tables 2 and 3. Table 2 lists recommended values

of RTUNE and CTUNE in order to meet 2% output

voltage deviation limits for some common output

voltages in the presence of a 20A to 40A step change

(50% of full 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

1500uF, 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 capacitance values.

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 45. The derating data applies

to airflow in either direction of the module’s axis.

The thermal reference point, Tref used in the

specifications are shown in Figure 46. For reliable

operation this temperature should not exceed 122oC.

The output power of the module should not exceed

the rated power of the module (Vo,set x Io,max).

Please refer to the Application Note “Thermal

Characterization Process For Open-Frame Board-

Mounted Power Modules” for a detailed discussion of

thermal aspects including maximum device

temperatures.

Heat Transfer via Convection

Increased airflow over the module enhances the heat

transfer via convection. Thermal derating curves

showing the maximum output current that can be

delivered at different local ambient temperatures (TA)

for airflow conditions ranging from natural convection

and up to 2m/s (400 ft./min) are shown in the

Characteristics Curves section.

Figure 46. Temperature measurement location Tref.

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 the Board Mounted Power

Modules: Soldering and Cleaning Application Note.

Through-Hole Lead-Free Soldering

Information

The 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

technical representative for more detail.
