Iron Device

Iron Device designs chips that manage and convert electrical power, for example, the circuitry inside phone chargers, computer power supplies, and motor-drive systems, as well as audio amplifier chips that deliver sound from speakers.

Its products sit inside consumer electronics, computing hardware, and other devices that need precise control of electrical energy. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company develops mixed-signal and system-on-chip semiconductors that integrate analogue, digital, and power-handling functions on a single chip.
