Audio Amplifier
Iron Device’s amplifiers are designed for mobile applications especially but also and other hearable applications. Our products offer best-in-class idle power consumption while maintaining high output power efficiency. Iron Device, we provide total audio solutions with less power consumption in tiny size. We believe tiny chip could make strong sound and have been working to manufacturer small and powerful amplifier embedded for your designs, customers and the markets.
Audio Codec
Iron Device’s audio codec ICs are designed for mobile applications like smartphones, tablets, headphones, and other hearable and portable devices. Our audio codec ICs offers a broad range of applications and they are perfectly suited for mobile phone, smart speakers, smart accessories sound.
Audio ADC Converter
Iron Device offers best audio analog-to-digital converters and digital-to-analog converters for mobile applications like smartphones, tablets, headphones, and other hearable and portable devices. Iron Device’s AD, DC converter is designed cost effectively and simple to user interface. From low power earphones to powerful loud speakers, Iron Device also offers a wide range of audio AD, DC converters for various applications. And we provide very suitable audio solution for each application which makes them sound perfectly.
Boost Converter
Iron Device is specialized in sound technology but we also have deep experience in powers. The common problem facing design and commercializing is power efficiency and stability in application. Especially in small scale application, such as portable devices our deep experience can provide innovative solution for boost converter from many sources.
Motor Driver
Iron Device provides Motor driver for various applications from home device to automatics. And out motor drivers simply designed to use maximize board guaranteeing efficiency and reliability. Our motor driver performs its function and help application reduce power consumption.
Gate Driver
A gate driver is a power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor. As increasing consumption of media content on mobile devices, power duration has become important option to choose a device. Therefore, power efficiency is an important factor for consumers to select a product, which gradually increase the importance of gate drivers.
GaN Driver

As we named Iron Device, GaN Driver we make, offers high power efficiency and reliability. With no power, any devices couldn’t work well Gate driver is one of the most important thing of device. For this, IC reliability is the one factor Iron Device’s GaN driver offers outstanding power resistance, high speed switching. We could allow you make your application having a ultimately smaller size but with very powerful performance.

SiC Driver

Smart devices need more power, because they will control other devices by AI and IoT system. For this, smart devices have to be required using special drivers for the high efficiency power control system. For this SiC technology is required both SIC and GaN. Iron Device’s SIC Driver is satisfying stability of the application’s performance at the same time reducing power consumption.
