0.75 Watt Miniature SIP DC/DC Converter
PRODUCT OVERVIEW
The HPR4XXC Series uses advanced circuit design and packaging technology to realize superior reliability and performance. A 170kHz push-pull oscillator is used in the input stage. The HPR4XXC Series reduces beat-frequency oscillation problems when used with high frequency isolation ampliers. Reduced parts count and high efciency add to the reliability of the HPR4XXC Series. The high efciency of the HPR4XXC Series means less internal power dissipation, as low as 190mW. With less heat to dissipate the HPR4XXC Series can operate at higher temperatures with no degradation of reliable operation. In addition, the high efciency of the HPR4XXC 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 this product has a >1mA minimum load for specications purposes. The HPR4XXC Series provides high isolation in a very small package. The use of surface mounted devices and manufacturing technologies makes it possible to offer premium performance and low cost.
