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.
