HB04UC
4.0W Unregulated High Isolation DC/DC Converter
DESCRIPTION
The HB04UC Series is a low-cost, high-isolation voltage, unregu-
lated, 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 packag-
ing technology to realize superior reliability and performance.
A 100kHz driven push-pull oscillator is used to ensure stable
frequency and non-saturating operation of the input stage. This
means there are no high peak voltages or currents like other
design topologies, which can reduce unit reliability. Reduced
parts count adds to the reliability of the HB04UC Series.
The high efficiency of the HB04UC Series means less internal
power dissipation. With less heat to dissipate, the HB04UC
Series can operate over a wider ambient temperature range
with no degradation of reliable operation.
The HB04UC Series offers the user low cost without sacrificing
reliability. The use of surface mounted devices and manufactur-
ing technologies make it possible to offer premium performance
at low cost.

MATERIAL: Units are encapsulated in a low thermal resistance molding compound which has excellent
chemical resistance, wide operating temperature range, and good electrical properties under high humidity
environments. The encapsulant and outer shell of the unit have UL94V-0 ratings. Lead material is brass;
lead finish is a 100-300 micro-inch layer of matte tin over a 5-40 micro-inch barrier layer of nickel.
