4.0W Unregulated High Isolation DC/DC Converter
PRODUCT OVERVIEW
The HB04UC Series is a low-cost, high-isolation voltage, unregulated, single
and dual output DC/DC converter. The dielectric withstand characteristics of
each converter is tested in production to ensure barrier integrity.
The HB04UC Series uses advanced circuit design and packaging technology
to realize superior reliability and performance. A 100kHz driven push-pull
