Product Overview
Low Power Isolation Transformers are essential components for
communications, computing, medical, industrial, and automotive
market segments. They provide signal isolation between low and high
voltage circuits, power gate drive circuitry for IGBTs, and power
isolated communication interfaces like RS-232 and RS-485. With the
increasing adoption of high voltage battery packs in automotive and
energy storage, the demand for compact, high-isolation transformers
is rapidly growing. These transformers are utilized in energy
transfer topologies such as push-pull, half-bridge, and
full-bridge, as well as energy storage topologies including
quasi-resonant and discontinuous mode flybacks. Selection is based
on end-application safety requirements (isolation voltage,
insulation level, safety distances) and electrical requirements
(topology, input/output voltages, operating frequency, output
power). Pulse parts are designed for UL and TUV compliance with
standards like IEC60950, IEC61558, and IEC60601, with some designs
holding specific safety certifications. Both commercial and
automotive grades are available.
