General Description
The TRACO THL 6WISM series is a new range of isolated 6W DC/DC converter modules featuring fully regulated output voltages and
ultra-wide 4:1 input voltage ranges. These products are with a very small footprint occupying just 4.5cm2 (0.7 square in.) on PCB.
All models are qualified for lead free reflow solder processes according IPC J-STD-020D.An excellent efficiency allows an operating
temperature range of –40° to +80°C. Further features include remote On/Off control and over load protection.
The very compact dimensions of these DC/DC converters make them an ideal solution for many space critical applications in batterypowered equipment and instrumentation.

Application Note
THL 6WISM Series
Input Source Impedance
The power module should be connected to a low impedance input source. Highly inductive source impedance can
affect the stability of the power module. Input external L-C filter is recommended to minimize input reflected ripple
current. The inductor is simulated source impedance of 12μH and capacitor is Nippon chemi-con 47 μF/100V. The
capacitor must as close as possible to the input terminals of the power module for lower impedance.
Output Over Current Protection
THL 6WISM series converters contain hiccup mode output over current protection that prevents damage to the
product in the event of an overload or a short circuit. Normally, over current is above 110% of the rated current for
THL 6WISM series. Depending upon the converter design, there are other ways of protecting the converter against
over current conditions such as the constant current limiting or current foldback methods.
With “hiccup” over current protection, the converter shuts off upon an occurrence of an over current condition. After a
brief time interval, it automatically tries to restart the converter. If the restart is successful, normal operation continues.
If the over current condition still exists, the converter will shut off again. With a sustained over current condition, such
as a short circuit on the output, this automatic retry behavior will result in periodic pulses of current and voltage on the
output. The output current waveform with hiccup over current protection is shown in figure below.
Hiccup operation has none of the drawbacks of
the other two protection methods, although its
circuit is more complicated because it requires a
timing circuit. The excess heat due to overload
lasts for only a short duration in the hiccup cycle,
hence the junction temperature of the power
devices is much lower.
The hiccup operation can be done in various
ways. For example, one can start hiccup
operation any time once an over-current event is
detected; or prohibit hiccup during a designated
start-up is usually larger than normal operation
and it is easier for an over-current event is
detected; or prohibit hiccup during a designated
start-up interval (usually a few milliseconds). The
reason for the latter operation is that during startup, the converter needs to provide extra current
to charge up the output capacitor. Thus the
current demand during start-up is usually larger than during normal operation and it is easier for an over-current event
to occur. If the converter starts to hiccup once there is an over-current, it might never start up successfully. Hiccup
mode protection will give the best protection for a converter against over current situations, since it will limit the
average current to the load at a low level, so reducing power dissipation and case temperature in the power devices.
Output Over Voltage Protection
The output over-voltage protection consists of output Zener diode that monitors the voltage on the output terminals.
If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode clamps the
output voltage.

Short Circuitry Protection
Continuous, hiccup and auto-recovery mode.
During short circuit, converter still shut down, The average current during this condition will be very low and the
device will be safe in this condition.
Remote ON/OFF Control
With no suffix, the positive logic remote ON/OFF control circuit is included. Turns the module ON during logic High
on the ON/Off pin and turns OFF during logic Low. The ON/OFF input signal (Von/off) that referenced to GND. If not
using the remote on/off feature, please open circuit between on/off pin and -Vin pin to turn the module on.
With suffix-N, the negative logic remote ON/OFF control circuit is included.
Turns the module ON during logic Low on the On/Off pin and turns OFF during logic High. The On/Off pin is an open
collector/drain logic input signal (Von/off) that referenced to GND. If not using the remote on/off feature. Please short
circuit between on/off pin and –Vin pin to turn the module on.

Application Note
THL 6WISM Series
Thermal Consideration
The converter is designed to operate in a variety of thermal environments and sufficient cooling must be provided
to ensure reliable operation. Heat is removed by conduction from the pins to the PCB board, and by convection
through airflow across the converter. Proper cooling can be verified by measuring the point as the figure below.
The temperature at this location should not exceed 105°C. When operating, adequate cooling must be provided to
maintain the test point temperature at or below 105°C. Although the maximum point temperature of the power module
is 105°C, you can limit this temperature to a lower value for extremely high reliability.

Safety and Installation Instruction
Fusing Consideration
Caution: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of sophisticated power architecture. To 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 slow-blow fuse with maximum rating of 1.5A. Based on the information provided in this data sheet
on Inrush energy and maximum dc input current; the same type of fuse with lower rating can be used. Refer to the
fuse manufacturer’s data for further information.
MTBF and Reliability
The MTBF of THL 6WISM series of DC/DC converters has been calculated using
MIL-HDBK 217F NOTICE2, Operating Temperature 25C, Ground Benign.
