  7 7-15 model 830-004 model 830-004 power supply module description ? continuous 6 watts of output power without use of a heat sink ? wide input voltage range from 110 vdc to 375 vdc ? single ?ed regulated output, voltages available from 5 vdc to 18 vdc ? sustains continuous short circuit ? two sided layout design and sip package minimized board space requirement ? ef?ient circuit design constructed on a thermally conductive ceramic substrate ? ul recognition pending features ? provides dc power for pwm and control circuitry for off-line switching power suppliers ? provides isolated low dc voltages from ac line voltage levels (recti?r external) ? battery chargers for portable personal electronics ? industrial controls and line monitoring ? stand-alone power supply for small electronics and ? controlled appliances ? replacement for wall mount transformers and linear regulators applications the 830-004 is a single output isolated dc/dc converter with an input range of 110 to 375 vdc. this allows the module to operate from any recti?d 80 to 265 vac line, corresponding to line voltages found worldwide. fixed output voltages between 5 to 18 vdc speci?ations subject to change without notice. last update: 06/06/02. are available to suit a variety of applications. low cost, high reliability and small dimensions are the main characteristics of this design. the use of an advanced pwm provides for stable and ef?ient operation over a wide load range.
7-16 model 830-004 ac line 47 f 25 v 47 f 250 v typical configuration application notes model 830-004 is a complete dc/dc module based on a ?back circuit topology. most applications require the addition of output capacitance. the capacitor? voltage rating should be selected in correlation to the output voltage of the 830-004. choose suf?ient capacitance to reduce the output ripple to an acceptable level for the application. a 47? electrolytic should generally be suitable and should be located close to the output pins. to operate from an ac line, a bridge recti?r must be added. a db104 bridge rectifier or four in4005 con?ured as pictured. diodes should be 600 volts, 1 amp and should be used in conjunction with a 47? input capacitor. choose the capacitor voltage rating appropriately. for example, 117 vac generates 165 volts peak. at a 1.5 x derating, use a 250 volt capacitor.
