Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Th ese are absolute stress

ratings only, functional operation of the device is not implie d 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 reliabiltiy.

* Forced convection—1.5 ms–1 (300 lfm) minimum. Higher ambient temperatures are possible with increased airflow and/or decreased power

output. See the Thermal Considerations section for more details.

† The –40 °C operation is optional. See Ordering Information section.

Electrical Specifications

Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.

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

This power SIP can be used in a wide variety of applications, ranging from simple stand-alone operation to an

integrated part of a sophisticated 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 no rmal-blow

fuse with a maximum rating of 10 A (see Safety Considerations section). To aid in the proper fuse selection for the given appli-

cation, information on inrush energy and maximum dc input current is provided. Refer to the fuse manufacturer’s data for fur-

ther information.

Test Configurations

Note: Measure input reflected ripple current with a simulated source

inductance (LTEST) of 500nH. Capacitor CS offsets possible

battery impedance. Measure current as shown above.

Figure 14. Input Reflected Ripple Current Test Setup.

Note: Scope measurements should be made using a BNC socket,

with a 47 µF tantalum capacitor .Position the load between 51

mm and 76 mm (2 in and 3 in) from the module

Figure 15. Peak-to-Peak Output Ripple Measurement

Test Setup.

Note: All voltage measurements to be taken at the module termi-

nals, as shown above. If sockets are used then Kelvin con-

nections are required at the module terminals to avoid

measurement errors due to socket contact resistance.

Figure 16. Output Voltage and Efficiency Test Setup.

Design Considerations

Input Source Impedance

The power SIP should be connected to a low ac- impedance

input source. Highly inductive source impedances can affect

the stability of the SIP. Adding external capacitance close to

the input pins of the SIP can reduce the ac impedance and

ensure system stability. The minimum recommended input

capacitance (C1) is a 100 µF electrolytic capacitor (see Fig-

ures 17 and 19).

Figure 17. Setup with External Capacitor to Reduce

Input Ripple Voltag e .

To reduce the amount of ripple current fed back to the input

supply (input reflected-ripple current), an external input filter

can be added. Up to 10 µF of ceramic capacitance (C2) may

be externally connected to the input of the SIP, provided the

source inductance (LSOURCE) is less than 1 µH (see Figure

17).

To further red uce the input reflected-ripple current, a

filter inductor (LFILTER) can be connected between the sup-

ply and the external input capacitors (see Figure 18).

As mentioned above, a 100 µF electrolytic capacitor (C1)

should be added across the input of the SIP to ensure stabil-

ity of the unit. The electrolytic capacitor should be selected

for ESR and RMS current ratings to ensure safe operation in

the case of a fault condition. Refer to Figure 19 for the

appropriate electrolytic capacitor ratings.

When using a tantalum input capacitor, take care not to

exceed device power rating because of the capacitor’s fail-

ure mechanism (for example, a short circuit). The

filter inductor should be rated to handle the maximum power

SIP input current of 6.1 Adc.

If the amount of input reflected-ripple current is unaccept-

able with an external L-C filter, more capacitance may be

added across the input supply to form a C-L-C filter . For best

results, the filter components should be mounted close to

the power SIP.

Safety Considerations

For safety-agency approval of the system in which the power

module is used, the power module must be installed in com-

pliance with the spacing and separation requirements of the

end-use safety agency standard, i.e., UL60950, CSA C22.2

No. 60950-00, and

VDE 0805:2001-12 (IEC60950, 3rd Ed).

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 ELV (extra-low voltage) outputs

when all inputs are ELV.

The input to these units is to be provided with a maximum

10A normal-blow fuse in the unearthed lead.

If an input electrolytic capacitor is to be used, it should be

selected using the design information found in the Desig n

Considerations section.

NH020-Series Power SIPs:

Feature Descriptions

Remote On/Off

To turn the power SIP on and off, the user must supply a

switch to control the voltage at the on/off terminal (Von/off).

The switch can be an open colle ctor pnp transistor con-

nected between the on/off terminal and the VI terminal or its

equivalent (see Figure 20).

During a logic low when the ON/OFF pin is open, the power

SIP is on and the maximum Von/off generated

by the power SIP is 0.3 V. The maximum

allowable leakage current of the switch when

Von/off = 0.3 V and VI = 5.5 V (Vswitch = 5.2 V) is 50 µA.

During a logic high, when V o n/off = 2.8 V to 5.5 V, the power

SIP is off and the maximum Ion/off is 10 mA. The switch

should maintain a logic high while sourcing 10 mA.

If not using the remote on/off feature, leave the

ON/OFF pin open.

The SIP has internal capacitance to reduce noise at the ON/

OFF pin. Additional capacitance is not generally needed and

may degrade the start-up characteristics of the SIP.

CAUTION: Never ground the on/off terminal. Ground-

ing the on/off terminal disables an impor-

tant safety feature and may damage the SIP

or the customer system.

Figure 20. Remote On/Off Implementation.

Output Voltage Set-Point Adjustment

(Trim)

Output voltage set-point adjustmen t allows the output volt-

age set point to be increased or decreased by connecting an

external resistor between the TRIM pin and either the VO pin

(decrease output voltage) or GND pin (increase output volt-

age). The trim range for the NH020F is +10%, –16%. The

trim range for the NH020G is ±10% of VO, nom. The trim

range for SIPs that produce less than 2.5 VO is +20%, –0%.

Connecting an external resistor (Rtrim-down) between the

TRIM and VO pin decreases the output voltage set point as

defined in the following equatio n.

For the F (3.3 VO) SIP:

For the G (2.5 VO) SIP:

Note: Output voltages below 2.5 V cannot be trimmed

down.

The test results for these config urations are displayed in Fig-

ures 21 and 22.

Overcurrent Protection

To provide protection in a fault condition, the unit is equipped

with internal overcurrent protection. The unit operates nor-

mally once the faul t condition is remove d.

The power module will supply up to 350% of rated current for

less than 1.25 seconds before it enters thermal sh utdown.

Overtempera tur e Prot ec ti o n

To provide additional protection in a fault condition, the unit is

equipped with a nonlatched thermal shutdown circuit. The

shutdown circuit engages when Q1 or Q2 exceeds approxi-

mately 110 °C. The unit attemp ts to restart when Q1 or Q2

cool down and cycles on and off while the fault condition

exists. Recovery from shutdown is accomplished when the

cause of the overtemperature condition is removed.

NH020-Series Power SIPs:

Thermal Considerations

To predict the approximate cooling needed for the SIP, deter-

mine the power dissipated as heat by the unit for the particu-

lar application. Figures 29—32 show typical heat dissipation

for the SIP over a range of output currents.

Note: Dimensions are in millimeters and (inches).

Figure 27. Thermal Test Setup.

Proper cooling can be verified by measuring the power SIP’s

temperature at lead 7 of Q31 as shown in Figure 28.

Figure 28. Temperature Measurement Location.

The temperature at this locati on should not exceed 115 ° C.

The output power of the SIP should not exceed the rated

power for the SIP as listed in the Ordering Information table.

Convection Requirements for Cooling

To predict the approximate cooling needed for the SIP, deter-

mine the power dissipated as heat by the unit for the particu-

lar application. Figures 29—32 show typical heat dissipation

for the SIP over a range of output currents.

NH020-Series Power SIPs:

Figure 32. NH020F Power Dissipation vs. Output

Current.

With the known heat dissipation and a given local ambient

temperature, the minimum airflow can be chosen from the

derating curves in Figure 33.

Figure 33. Power Derating vs. Local Ambient

Temperature and Air Velocity.

For example, if the unit di ssipates 2.0 W of heat, the mini-

mum airflow in an 80 °C environment is 1.0 m/s

(200 ft./min.).

Keep in mind that these derating curves are approximations

of the ambient temperatures and airflows re quired to keep

the power SIP temperature below its maximum rating. Once

the SIP is assembled in the actual system, the SIP’s temper-

ature should be checked as shown in Figure 28 to ensure it

does not exceed 115 °C.

Layout Considerations

Copper paths must not be routed between pins 2 and 3 and

pins 7 and 8.

Through-Hole Lead-Free Soldering Infor-

mation

The RoHS-compliant through-hole products use the SAC

(Sn/Ag/Cu) Pb-free solder and RoHS-compliant compo-

nents. 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 prehe at pro cess should be such

that the temp erature of the power module board is kept

below 210°C. For Pb solder, the recommende d pot temper-

ature is 260°C, while the Pb-free solder pot is 270°C max.

Not all RoHS-compliant through-hole products can be pro-

cessed with paste-through-hole Pb or Pb-free reflow pro-

cess. If additional information is needed, please consult with

your T yco Electronics Power System representative for more

details.

Post Solder Cleaning and Drying Considerations

Post solder cleaning is usually the final circuit-bo ard

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 Tyco

Electronics Board Mounted Power Modules: Soldering and

Cleaning Application Note (AP01-056EPS).

Solder Ball and Cleanliness Requirements

The open frame (no case or potting) power module will meet

the solder ball requirements per J-STD-001B. These

requirements state that solder balls must neither be loose

nor violate the power module minimum electrical spacing.

The cleanliness designator of the open frame power module

is C00 (per J specification).
