nv dc-dc series data sheet 6w smt converter ? wide input ? 3.3v to +/-24v outputs apr 20, 2006 revised to mar 12, 2007 page 6 of 11 www.power-one.com 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 100 ms until the overload has cleared. 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%). however, this may cause start-up problems at initial start-up, and is only recommended in applications where one converter is able to deliver the full load current (true redundant systems). series operation the outputs of two units may be connected in series to achieve a higher system voltage. safety considerations these converters feature 1500 vdc isolation from input to output. the input-to-output resistance is greater than 10m ? . these converters are provided with basic insulation between input and output circuits according to en60950 / ul1950 / csa60950-00. nevertheles s, 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. 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: ? 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: input voltage range recommended fuse 36-75v f0.315a 18-36v f0.5a 9-36v f1.0a 18-75v 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.

(dip of class ii or better). 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. the product is shipped in jedec trays to ensure preservation of the co-planarity and enable fully automated assembly in the final application (co- planarity within 0.1 mm). pick & place assembly: the product is designed with a large flat area in the center of the top surface to serve as a pick up point for automated vacuum pick and place equipment. 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 (> 6.0mm, 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. restriction curve above 215oc peak temp. at pins 1 and 10 (oc) 200 205 210 215 220 225 230 235 240 245 10 20 30 40 50 60 tp (s) time (s) 0 50 100 150 200 250 300 0 40 80 120 160 200 240 280 320 360 400 440 max. temp. on pins 1 and 10 during reflow soldering (deg c) tp peak temperature (see fig below) 190 ? 450 s
