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.
