However in the final application the temperature rise of the converter is also influenced by factors such as heat conduction through the leads to the PCB, orientation, the temperature of surrounding components and the input voltage. To ensure the reliability of the converter, care must be taken to guarantee that the maximum case temperature is not exceeded under any conditions.

(deg °C) The 9-36V and 18-75V input voltage versions of this series feature a 4:1 input voltage range and can achieve operation at full power at 85ºC ambient temperature with only convection cooling. 18-Oct-01 This series of converters does not require any external components for proper operation. However, if the distribution of the input voltage to the converter contains significant inductance, a capacitor across the input terminals may be required to stabilize the input voltage. A minimum of 0.47µF, quality electrolytic / ceramic capacitor is recommended for this purpose. For output decoupling it is recommended to connect, directly across the output pins, a 0.47µF ceramic capacitor (for 3.3V and 5V outputs) or a 0.27µF ceramic capacitor (for other outputs). Care must be taken to ensure the maximum rated output capacitance for the device is not exceed when dimensioning decoupling capacitors in the system as this could cause the unit to detect an overload and enter a ‘hiccup’ mode of operation. Rev 1.0 www.power-one.com Page 5 of 11 NV Series: 4 - 6W DC/DC Converters 9-36V, 18-36V, 36-72V & 16-75V Inputs 3.3V, 5.0V, 12V, 15V, ±5.0V, ±12V, ±15V & ±24V Outputs Product Specifications Oct 2001 Output Current Limiting When the output is overloaded above the maximum output current rating, the voltage will start to reduce to maintain the output power to a safe level. In a condition of high overload or short-circuit where the output voltage is pulled below approximately 30% of Vo.Nom, the unit will enter a ‘Hiccup’ mode of operation. Under this condition the unit will attempt to restart, approximately every 100ms until the overload has cleared. In order for the output of the converter to be considered as SELV (Safety Extra Low Voltage) or TNV-1, according to EN60950 / UL1950 / CSA60950-00, one of the following requirements must be met in the system design: • Parallel Operation Paralleling of two converters is possible by direct connection of the output voltage terminal pins. The load regulation characteristic is designed to facilitate current sharing (typically ± 20%). Recommended Fuse 36-75V 18-36V 9-36V 18-75V F0.315A F0.5A F1.0A F0.5A The user can select a lower rating fuse based upon the inrush transient and the maximum input current of the converter, which occurs at the minimum input voltage. Both input traces and the chassis ground trace (if applicable) must be capable of conducting a current of 1.5 times the value of the fuse without opening. The fuse must not be placed in the grounded input line, if any. • If the voltage source feeding the module is SELV, the output of the converter is considered SELV and may be grounded or ungrounded. • The circuitry of the converter may generate transients, which exceed the input voltage. Even if the input voltage is SELV (<60V) the components on the primary side of the converter may have to be considered as hazardous. A safety interlock may be needed to prevent the user from accessing the converter while operational. The outputs of two units may be connected in series to achieve a higher system voltage. Safety Considerations 18-Oct-01 Input Voltage Range • Series Operation These converters feature 1500 Volt DC isolation from input to output. The input to output resistance is greater than 10MOhm. These converters are provided with Operational Insulation between input and output circuits according to EN60950 / UL1950 / CSA60950-00. Nevertheless, if the system using the converter needs to receive safety agency approval, certain rules must be followed in the design of the system. In particular, all of the creepage and clearance requirements of the end-use safety requirements must be observed. These documents include UL60950, CSA60950-00 and EN60950, although specific applications may have additional requirements. The converter has no internal fuse. An external fuse must be provided to protect the system from catastrophic failure. The recommended fuse values are shown below: Rev 1.0 www.power-one.com Page 6 of 11 NV Series: 4 - 6W DC/DC Converters 9-36V, 18-36V, 36-72V & 16-75V Inputs 3.3V, 5.0V, 12V, 15V, ±5.0V, ±12V, ±15V & ±24V Outputs Product Specifications Oct 2001 EMC Specifications Conducted Noise: The converters meet the requirements of EN55022, CISPR22 and FCC CFR title 47 part 15 Sub-part J - Conducted (conducted noise on the input terminals) without any external components.

Failure to observe these instructions may result in failure or significant degradation of the module performance. PowerOne will not honor any warranty claims arising from failure to observe these instructions. 200 150 The product is shipped in JEDEC trays to guarantee preservation of the co-planarity and enable fully automated assembly in the final application. 440 190 – 450 s 400 360 320 280 240 200 160 80 0 40 0 120 50 Time (s) The lead-frame is constructed for a high temperature glass filled, UL94V0 flame retardant, diallyl ortho-phthalate moulding com pound commonly used for packaging of electronics components. It has passed NASA outgassing tests and is certified to MIL-M-14. The coefficient of thermal expansion is equivalent to FR4. The product is manufactured with a patented process, which is fully automated, and ‘in-line’. This ensures that there is no contamination or mechanical stress on the lead-frame so that the co planarity and solderability are maintained. tp 100 The curves below define the maximum peak reflow temperature permissible measured on Pins 1 and 10 of the converter. The gull wing leads are formed to ensure optimal solder joint strength and structure. Furthermore they facilitate optical inspection (manual or automatic). The leads are formed from a 97% Cu alloy plated with Cu and Sn 90. This material is commonly used in the manufacture of integrated circuits. It has good corrosion resistance and exhibits the nobility inherent to all high copper alloys. Unlike brasses, this material is essentially immune to stress corrosion cracking. It also exhibits excellent solderability. It is readily wetted by solders and performs well in standard solderability tests. (Dip of Class II or better).

The ‘open board’ construction of the unit ensures that weight is kept to a minimum. However due to the relatively large size of the component, a large nozzle (> 2.0mm, depending on vacuum pressure) is recommended for picking and placing. The unit may also be automatically handled using ‘odd-form’ placement equipment, with mechanical grippers. For this type of equipment the end edges of the device, which have no leads and also feature the greatest dimensional accuracy, should be used as pick-up points.
