General Description
The TEN 40N series, comprising 18 different models, specially addressing data communication equipments, mobile
battery driven equipments, distributed power systems, telecommunication equipments, mixed analog/digital
subsystems, process/machine control equipments, computer peripheral systems and industrial robot systems.
Packing up to 40W of power into a 2 x 1 x 0.4 inch package, with efficiency as high as 92%, the TEN 40N has a wide
input voltage ranges of 9-18Vdc, 18-36Vdc or 36-75Vdc and is available in output voltages of 3.3Vdc, 5Vdc, 12Vdc,
15Vdc, ±12Vdc and ±15Vdc.
Other features include over temperature and continuous short circuit protection, overvoltage protection, remote
on/off, six-sided shielded case, and EN55022 Class A conducted noise compliance minimize design-in time, cost
and eliminate the need for external filtering.

40W SINGLE & DUAL
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 47µF/100V. The
capacitor must as close as possible to the input terminals of the power module for lower impedance.
Output Over Current Protection TEN 40N 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 maintained at approximately 115 ~ 150
percent of rated current for TEN 40N 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 start-up,
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.

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 be used always.
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 normal-blow fuse with maximum rating of 8000mA for the TEN 40-12xxN, 4000mA for the TEN
40-24xxN and 2000mA for the TEN 40-48xxN models. 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.
