HB04U
DESCRIPTION
The HB04U 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 produc-
tion to ensure barrier integrity.
The HB04U Series uses advanced circuit design and packaging
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. Reliability
is further enhanced by the use of MOSPOWER transistors.
These rugged devices permit higher frequency operation with
less complicated drive circuitry than is possible with bipolar
power transistors. Reduced parts count adds to the reliability of
the HB04U Series.
The high efficiency of the HB04U Series means less internal
power dissipation. With less heat to dissipate, the HB04U
Series can operate over a wider ambient temperature range
with no degradation of reliable operation.
The HB04U Series offers the user low cost without sacrificing
reliability. The use of surface mounted devices and manufacturing
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
with a solder plated surface to allow ease of solderability.
