figure 1. simplified schematic dip-packaged, standard-pinout 3 watt, dc/dc converters features the proven cost-effectiveness, quality and long-term reliability that has come to define datel ? s standard, 3w, dual-output, dip-packaged dc/dc converters (see bst 3w models) is now available in the "other standard pinout" (see next page) made popular by off-shore suppliers. these newly designed bwp models exploit totally automated smt assembly techniques and do not contain any trimpots, "wet" aluminum electrolytic capacitors, or manually soldered "flying" leads. their made-in- the-usa quality and affordable pricing are rapidly making them the converters of choice in many existing applications. bwp dc/dc converters bring true component-like convenience to designers of modern distributed power systems. exploiting an efficient, high-frequency (170- 200khz), flyback topology and high-density smt assembly techniques, bwp dc/ dc ? s have enough space to include input (pi type) and output filters within their package. they are fully isolated (500vdc guaranteed) and do not require any external components to meet published specifications. they operate, without derating, over the full ? 40 to +75 c temperature range. output voltages are either 5, 12 or 15 volts. input voltage ranges are either 4.5-9v ("d5" models), 9-18v ("d12" models) or an ultra-wide 18-72v ("d48" models). output transient response time is a quick 200sec, and output ripple and noise are typically 75mvp-p. all models are certified to ul1950, csa 22.2 no. 950 and iec950. full emi/emc characterizations are currently in progress. datel ? s bwp model 3w dc/dc ? s are ideal replacements for other more costly, less reliable power converters as well as excellent choices for new design-ins in systems demanding small size, low cost and high reliability. low cost! high quality! highly reliable, 100% smt construction standard dip package and pinout no external components required 5, 12 or 15 volt outputs choice of 3 wide input ranges: 4.5-9 volts 9-18 volts 18-72 volts guaranteed efficiencies to 75% fully isolated, 500vdc guaranteed internal input/output filtering output current limiting ?40 to +75c operation with no derating ul1950/c22.2 no. 950/iec950 certified modifications and customs for oem?s datel, inc., mansfield, ma 02048 (usa) ? tel: (508)339-3000, (800)233-2765 fax: (508)339-6356 ? email: sales@datel.com ? internet: www.datel.com
