FEATURES
The HPR1XXWC Series uses advanced circuit design and packaging technology to deliver superior reliabil-
ity and performance. A 170kHz push-pull oscillator is used in the input stage. Beat-frequency oscillation
problems are reduced when using the HPR1XXWC Series with high frequency isolation amplifiers.

Internal Input and Output
ꢀ
Reduced parts count and high efficiency add to the reliability of the HPR1XXWC Series. The high
efficiency of the HPR1XXWC Series means less internal power dissipation, as low as 190mW.
Filtering
ꢀ
With reduced heat dissipation the HPR1XXWC Series can operate at higher temperatures with no
degradation. In addition, the high efficiency of the HPR1XXWC 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 reli-
ability of the series, although a >1mA minimum load is needed to realize published specifications.
Non-Conductive Case
ꢀ
High Output Power Density: 10 Watts/Inch3
ꢀ
Extended Temperature Range: -25°C to +85°C
ꢀ
The HPR1XXWC Series provides the user a low cost converter without sacrificing reliability. The use
of surface mounted devices and advanced manufacturing technologies make it possible to offer
premium performance and low cost.
Efficiency to 79%
ꢀ
RoHS Compliant
ꢀ
All specifications are typical at TA = +25°C nominal input voltage unless otherwise specified.
