Key Terms

flyback converter topologies, surface-mount flyback transformers, rohs-compliant, isolated dc/dc converters

4 terms

flyback converter topologies technical

"new series designed for flyback converter topologies."

A group of circuit designs used in switch-mode power supplies where energy is stored in a transformer or inductor and released in pulses to convert electricity from one voltage to another; different flyback converter topologies change how switches, transformers, and control components are arranged to trade off size, cost, efficiency, isolation and noise. For investors, these design choices affect a product’s manufacturing cost, reliability, energy efficiency and suitability for regulated or consumer markets—factors that influence sales, margins and compliance risk.

surface-mount flyback transformers technical

"customizable, surface-mount flyback transformers"

Surface-mount flyback transformers are small magnetic components designed to be soldered directly onto a circuit board; they store and transfer energy in switch-mode power supplies using a flyback (pulse-based) conversion method to create isolated voltages. For investors, they matter because they are critical parts in many electronic products and power adapters, so their availability, cost, and quality can affect manufacturing, product reliability, and a maker’s margins and supply-chain risk.

rohs-compliant regulatory

"The RoHS-compliant transformers offer inductance values"

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

isolated dc/dc converters technical

"as well as isolated DC/DC converters up to 30 W."

Isolated dc/dc converters are electronic modules that take a direct-current (DC) input voltage and produce a different DC output while keeping the input and output electrically separated by an internal barrier. The isolation protects sensitive circuitry, meets safety and regulatory requirements, and reduces noise, like a transformer that also changes voltage levels. Investors track them because demand, pricing, and supply constraints for these components affect revenue, margins and product approvals across many industries that use power electronics.

Customizable Flyback Transformers Support Wide 26 V to 72 V Input Range and High Isolation of 1500 VRMS for 60 s

MALVERN, Pa., Aug. 27, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has expanded its power transformer line with a new series designed for flyback converter topologies. Featuring 17 devices, the Vishay Dale IFBT series of customizable, surface-mount flyback transformers is designed to operate with a wide 26 V to 72 V input voltage range at 250 kHz while providing high isolation of 1500 V_RMS for 60 s from primary and bias windings to secondary.

The devices released today feature multiple windings, allowing for combinations of series and parallel connections to support different voltage and current handling configurations. Along with their wide input voltage range, this flexibility enables output voltages from 1.8 V to 24 V and output currents from 0.5 A to 9.0 A. The RoHS-compliant transformers offer inductance values from 35.0 µH to 75.0 µH and operate over a temperature range of -40 °C to +125 °C.

IFBT series devices will serve as flyback transformers for 6 W and 30 W PoE designs, as well as isolated DC/DC converters up to 30 W. Typical applications will include automotive lighting LED driver transformers; energy generation, distribution, and management systems; industrial drives, tools, and automation systems; home and building controls; consumer devices; white goods; telecom equipment; and medical instrumentation.
