The HPR1XXC Series uses advanced circuit design and packaging technology to deliver superior reliability and performance. A 170kHz push-pull oscillator is used in the input stage. Beat-frequency oscillation problems are reduced when using the HPR1XXC Series with high frequency isolation amplifi ers.Reduced parts count and high efficiency add to the reliability of the HPR1XXC Series. The high efficiency of the HPR1XXC Series means less internal power dissipation, as low as 190mW.With reduced heat dissipation the HPR1XXC Series can operate at higher temperatures with no degradation. In addition, the high efficiency of the HPR1XXC Series means the series is able to offer greater than 10 W/inch3 of output power density. Operation down to no load will not impact the reliability of the series, although a >1mA minimum load is needed to realize published specifi cations.The HPR1XXC Series provides the user a low cost converter without sacrifi cing reliability. The use of surface mounted devices and advanced manufacturing technologies make it possible to offer premium performance and low cost.
