Application Note
15W SINGLE OUTPUT
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 C-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 KZE series 220µF/100V&33µF/100V. The capacitor
must as close as possible to the input terminals of the power module for lower impedance.
Output Over Current Protection
When excessive output currents occur in the system, circuit protection is required on all power supplies. Normally, overload
current is maintained at approximately about 150 percent of rated current for TON 15-WI single output series.
Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply from being damaged
during an over-current fault condition. It also enables the power supply to restart when the fault is removed.
One of the problems resulting from over current is that excessive heat may be generated in power devices; especially
MOSFET and Shottky diodes and the temperature of those devices may exceed their specified limits. A protection mechanism
has to be used to prevent those power devices from being damaged.
Output Over Voltage Protection
The output over-voltage protection consists of a Zener diode that monitors the output voltage on the feedback loop. If the
voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode will send a current signal to
the control IC to limiting the output voltage.

Application Note
15W SINGLE OUTPUT
Output Voltage Adjustment
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is
accomplished by connecting an external resistor between the TRIM pin and either the +Vout or -Vout pins. With an external resistor
between the TRIM and -Vout pin, the output voltage set point increases. With an external resistor between the TRIM and +Vout pin,
the output voltage set point decreases.

Application Note
15W SINGLE OUTPUT
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 can
be safety in this condition.
Thermal Consideration
The power module operates in a variety of thermal environments. However, sufficient cooling should be provided to help
ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding Environment.
Proper cooling can be verified by measuring the point as the figure below. The temperature at this location should not exceed
120°C. When Operating, adequate cooling must be provided to maintain the test point temperature at or below 120°C. Although
the maximum point Temperature of the power modules is 120°C, you can limit this Temperature to a lower value for extremely
high reliability.

Remote ON/OFF Control
The Remote ON/OFF Pin is controlled DC/DC power module to turn on and off; the user must use a switch to control the
logic voltage high or low level of the pin referenced to -Vin. The switch can be open collector transistor, FET and Photo-Couple.
The switch must be capable of sinking up to 1 mA at low-level logic Voltage. High-level logic of the ON/OFF signal maximum
voltage is allowable leakage current of the switch at 15V is 50µA.

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 3A for TON 15-24xxWI modules and 1.5A for TON 15-48xxWI modules. 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 TON 15-WI SERIES of DC/DC converters has been calculated according to
Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40°C (Ground fixed and controlled environment ).
The resulting figure for MTBF is 1´322´000 hours.
MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C. The resulting figure for MTBF is 514´700 hours.
