A highly inductive source impedance can affect the stability of the converter. An input external L-C filter is recommended to minimize input reflected ripple current. The inductor has a simulated source impedance of 12μH and the capacitor is Nippon chemi-con KZE series 47μF/100V. The capacitor must be located as close as possible to the input terminals of the converter for the lowest impedance. Output Over Current Protection When excessive output currents occur in the system, circuit protection is required on all converters. Normally, overload current is maintained at approximately 150 percent of rated current for PXF60 single output series. Hiccup-mode is a method of operation to protect the converter from being damaged during an over-current fault condition. It also enables the converter 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 these devices may exceed their specified limits. A protection mechanism has to be employed to prevent those power devices from being damaged. VER:00 Page 24 of 31 Issued Date：2009/03/02

Mar. 06, 2019 60W, Single Output 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 signal to the control IC to limit the output voltage.

Mar. 06, 2019 60W, Single Output Thermal Consideration The converter operates in a variety of thermal environments. 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 110°C. When operating, adequate cooling must be provided to maintain the test point temperature at or below 110°C. Although the maximum point temperature of the power modules is 110°C, limiting this temperature to a lower value will increase the reliability.

Mar. 06, 2019 60W, Single Output Remote ON/OFF Control The Remote ON/OFF Pin is used to turn on and off the DC/DC converter. The user must use a switch to control the logic voltage (high or low level) of the ON / OFF pin referenced to Vi (-). The switch can be an open collector transistor, FET or Photo-Coupler that is capable of sinking up to 1 mA at low-level logic voltage. At High-level logic(ON/OFF signal maximum voltage): the allowable leakage current of the switch at 12V is 0.5 mA.

Mar. 06, 2019 60W, 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 SENSE(+) or SENSE(-) pins. With an external resistor between the TRIM and SENSE(-) pin, the output voltage set point increases. With an external resistor between the TRIM and SENSE(+) pin, the output voltage set point decreases.

Mar. 06, 2019 60W, Single Output Safety and Installation Instruction Fusing Consideration Caution: This converter is not internally fused. An input line fuse must always be used. This converter can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a 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 slow-blow fuse with maximum rating of 5A for PXF60-24Sxx modules and 3A for PXF60-48Sxx 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 PXF60-SERIES of DC/DC converters has been calculated using Bellcore TR-NWT-000332 Case I: 50% stress, Operating temperature at 40 °C (Ground fixed and controlled environment ). The resulting figure for MTBF is 1.093×106 hours. MIL-HDBK-217F NOTICE2 FULL LOAD, Operating temperature at 25°C. The resulting figure for MTBF is 1.096×105 hours.
