Description

The QW series power modules are isolated dc-dc converters that can deliver up to 20A of output current and provide a pre-

cisely regulated output voltage over a wide range of input voltages (VI = 36Vdc to 75Vdc). The modules achieve full load effi-

ciency of 91% at 3.3V output voltage, The open frame modules, available in both surface-mount and through-hole packaging,

enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, output voltage adjust-

ment, remote sense,overvoltage, overcurrent and overtemperature protection.

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 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 time-delay fuse with a

maximum rating of 5 A (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.

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

These converters have been evaluated to the spacing

For Basic Insulation models ("–B" Suffix), 1500 Vdc is

applied from VI to VO to 100% of outgoing production.

Note: Measure input reflected ripple current with a simulated source

inductance (LTEST) of 12µH. Capacitor CS offsets possible

battery impedance. Measure current as shown above.

For end products connected to –48 Vdc, or –60 Vdc nomianl

DC MAINS (i.e. central office dc battery plant), no further

fault testing is required.

Note:–60 V dc nominal bettery plants are not available in the

U.S. or Canada.

The power module should be connected to a low

ac-impedance input source. Highly inductive source imped-

ances can affect the stability of the power module. If the input

Although the output voltage can be increased by both the

remote sense and by the trim, the maximum increase for the

output voltage is not the sum of both. The maximum increase

is the larger of either the remote sense or the trim.

Feature Descriptions

The amount of power delivered by the module is defined as

the voltage at the output terminals multiplied by the output

current. When using remote sense and trim, the output volt-

age of the module can be increased, which at the same out-

put current would increase the power output of the module.

Care should be taken to ensure that the maximum output

power of the module remains at or below the maximum rated

power.

Remote On/Off

Two remote On/Off options are available. Positive logic

remote On/Off turns the module on during a logic-high volt-

age on the remote ON/OFF pin, and off during a logic low.

Negative logic remote On/Off, device code suffix "1", turns

the module off during logic-high voltage and on during a logic

low.

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

switch to control the voltage between the

ON/OFF pin and the VI(–) terminal. The switch may be an

open collector or equivalent (see Figure 40). A logic low is

Von/off = –0.7 V to 1.2 V. The maximum Ion/off during a logic

low is 1 mA. The switch should maintain a logic-low voltage

while sinking 1 mA. During a logic high, the maximum Von/off

generated by the power module is 15 V. The maximum allow-

able leakage current of the switch at Von/off = 15 V is 50 µA.

Output voltage trim allows the user to increase or decrease

the output voltage set point of a module. This is accom-

plished by connecting an external resistor between the TRIM

Feature Descriptions (continued)

Overcurrent Protection

To provide protection in an output overload fault condition,

the module is equipped with internal current-limiting circuitry,

and can endure current limiting for an unlimited duration. At

the instance of current-limit inception, the module enters a

"hiccup" mode of operation, whereby it shuts down and auto-

matically attempts to restart. While the fault condition exists,

the module will remain in this mode until the fault is cleared.

The unit operates normally once the output current is

reduced back into its specified range.

Output Overvoltage Protection

The output overvoltage protection consists of circuitry that

monitors the voltage of the output terminals. If the output volt-

age exceeds the overvoltage protection threshold, the mod-

ule enters a "hiccup" mode of operation, whereby it shuts

down and automatically attempts to restart. While the fault

condition exists, the module will remain in this hiccup mode

until the overvoltage fault is cleared.

Overtemperature Protection

The output overvoltage protection consists of circuitry that

monitors the voltage on the output terminals. If the output

voltage exceeds the overvoltage protection threshold, the

module enters a "hiccup" mode of operation, whereby it shuts

down and automatically attempts to restart. While the fault

condition exists, the module will remain in this hiccup mode

until the overvoltage fault is cleared.

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.

ensure reliable operation of the unit. Heat is removed by con-

duction, convection, and radiation to the surrounding environ-

ment. Proper cooling can be verified by measuring drain pin

sheets in order to customize the solder reflow profile for each

application board assembly.

The following instructions must be observed when SMT sol-

dering these units. Failure to observe these instructions may

result in the failure of or cause damage to the modules, and

can adversely affect long-term reliability.

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 components.

They are designed to be processed through single or dual

wave soldering machines. The pins have an RoHS-compli-

ant 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 addi-

tional information is needed, please consult with your Tyco

Electronics Power System representative for more details.

Typically, the eutectic solder melts at 183^oC, wets the land,

and subsequently wicks the device connection. Sufficient

time must be allowed to fuse the plating on the connection to

ensure a reliable solder joint. There are several types of

SMT reflow technologies currently used in the industry.

These surface mount power modules can be reliably sol-

dered using natural forced convection, IR (radiant infrared),

or a combination of convection/IR.

Although the module weight is minimized by using open-

optimize the pick-and-place process, automated vacuum

equipment variables such as nozzle size, tip style, vacuum

pressure, and placement speed should be considered. Sur-

face-mount versions of this family have a flat surface which

serves as a pick-and-place location for automated vacuum

equipment. The module’s pick-and-place location is identified

MSL Rating

The QW series SMT modules have a MSL rating of 2.

Storage and Handling

The recommended storage environment and handling proce-

dures for moisture-sensitive surface mount packages is

detailed in J-STD-033 Rev. A (Handling, Packing, Shipping

and Use of Moisture/Reflow Sensitive Surface Mount

Devices). Moisture barrier bags (MBB) with desiccant are

required for MSL ratings of 2 or greater. These sealed pack-

ages should not be broken until time of use. Once the origi-

nal package is broken, the floor life of the product at

conditions of £ 30°C and 60% relative humidity varies

according to the MSL rating (see J-STD-033A). The shelf life

for dry packed SMT packages will be a minimum of 12

months from the bag seal date, when stored at the following

conditions: < 40° C, < 90% relative humidity.

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 Tyco

Electronics Board Mounted Power Modules: Soldering and

Cleaning Application Note (AP01-056EPS).
