IRIS4013 is a special voltage regulator manufactured by UnisonIC. It is designed to provide high-voltage output precision and low-noise power supply for digital circuits, particularly for audio applications.The IRIS4013 is a DC-DC switching converter, which consists of an N-Channel MOSFET, two diodes, and several capacitor components. It has a low harmonic distortion, low EMI interference, and is suitable for a wide range of applications. It is frequently used in battery-powered portable electronic devices such as smartphones, media players, and other audio applications.The IRIS4013 is capable of outputting multiple voltage levels up to 5.0V and can be powered by a wide range of input voltage levels from 2.5V to 12V. It is capable of delivering up to 1.5A of current and has an adjustable output voltage range of 3.0V to 5.5V. Furthermore, it has built-in over voltage, over current, and over temperature protections and features EL-Targeting for soft-start and low battery ripple.The working principle of the IRIS4013 is based on a simple DC-DC switching regulator. It uses a P-Channel MOSFET to step down the output voltage from the input voltage. The MOSFET is controlled by a controlled oscillator, which is regulated by the error amplifier. This enables the converter to provide a precise output voltage.When the input voltage rises, the error amplifier will detect the difference between the output voltage and the reference voltage and set the frequency of the oscillator accordingly. The higher the frequency of the oscillator, the more times it will switch the MOSFET on and off every second. This results in increased output power.The IRIS4013 is highly efficient due to its high switching frequency and very low quiescent current consumption. Its high efficiency helps reduce the device’s power losses and minimize the need for a large heatsink or external cooling components. This ensures the device’s maximum performance and very low output noise levels.In conclusion, the IRIS4013 offers an excellent solution for high-voltage output precision and low-noise power supply for digital circuits, particularly for audio applications. Its high efficiency and low quiescent current consumption make it an ideal choice for low-power, battery-powered applications. It features a wide input voltage range, adjustable output voltage range, EL-Targeting for soft-start, and built-in over voltage, over current, and over temperature protections, making it a great choice for multiple different applications.
