A WALL JFCW24S12-1300-C DESIGN CONSIDERATIONS: 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 150% of rated current. 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 Schottky 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 an output 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 IC to limit the output voltage. Short Circuit Protection Continuous, hiccup, and auto-recovery mode. The average current during this condition will be very low and the device is still safe in this condition. 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 10μF/100V and 10μF/100V. The capacitor must be connected as close as possible to the input terminals of the power module for lower impedance. 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, convention, 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 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 modules is 105°C, you can limit this temperature to a lower value for extremely high reliability.

A WALL JFCW24S12-1300-C Heatsink Consideration Equip heatsink for lower temperature and higher reliability of the module. Considering space and airflow is the way to choose which heatsink is needed. Figure 3 Unit: inches (mm) 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.

A WALL JFCW24S12-1300-C Remote ON/OFF Control The remote ON/OFF pin allows the user to turn the DC/DC power module on and off from a remote switch device. The ON/OFF input can be switched by a number of switching devices. Figure 5 gives several examples of acceptable configurations. The remote ON/OFF switch is activated by the voltage difference between the ON/OFF pin and the –Vin pin (with –Vin as the reference voltage). The user-supplied switch must be capable of sinking up to 1mA of current at low-level logic voltage. The leakage current of the user-supplied switch must be 50μA or less at 15Vdc. Remote ON/OFF Implementation Figure 5 Isolated-Closure Remote ON/OFF Level Control Using TTL Output Level Control Using Line Voltage There are two remote control options available: Positive logic and Negative logic a. The positive logic structure turned the DC/DC module ON when the ON/OFF pin is at high-level logic and turned the DC/DC module OFF when the ON/OFF pin is at low-level logic. Figure 6 When JFCW module is turned OFF at Low-level logic When JFCW module is turned ON at High-level logic b. The negative logic structure turned the DC/DC module ON when the ON/OFF pin is at low-level logic and turned the DC/DC module OFF when the ON/OFF pin is at high-level logic.

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. For 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. 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.
