ISL6402AIR-T is a low-noise and high PSRR 3.3V voltage regulator featuring both linear and switching modes. It is designed primarily for applications that require low output noise, such as communications and data acquisition systems, audio systems, and instrumentation systems. The device also supports high-efficiency switching mode operation when the load current is less than 5mA. The device can switch between modes seamlessly and is fully protected against over current, over temperature, and undervoltage.

In order to categorize the working principle of the ISL6402AIR-T and its application field, it must be classified as one of the following: PMIC (Power Management IC), Voltage Regulators, Linear + Switching.

PMIC - Power Management IC

PMIC stands for Power Management IC and refers to a chip dedicated to managing and optimizing power delivery to other parts of a product. PMICs handle all kinds of power management tasks like battery charging, voltage regulation and system monitoring. The ISL6402AIR-T can be classified as a PMIC, because it provides voltage regulation and power monitoring in one integrated package.

Voltage Regulators

A Voltage Regulator is a device designed to regulate or control the voltage in a circuit. It is primarily used to protect circuits from voltage fluctuations or spikes which could damage components or cause failure. The ISL6402AIR-T can be classified as a Voltage Regulator, as it provides constant voltage output even under varying conditions. The device also protects against over-voltage, over-temperature and under-voltage.

Linear + Switching

Linear and switching regulation are two of the main types of voltage regulation. Linear regulation is the most common type and works by controlling a reference voltage to the output. Switching regulation works by switching current in and out of the load, which generates a less regulated output voltage than linear regulation. The ISL6402AIR-T can be classified as a Linear + Switching Voltage Regulator, as it features both linear and switching modes.

Application Field

The ISL6402AIR-T is designed primarily for applications that require low output noise, such as communications and data acquisition systems, audio systems, and instrumentation systems. Thanks to the device\'s high PSRR, it is ideal for use in mobile, battery operated applications where power supply noise can easily be picked up by sensitive analog input circuits. The device is also suitable for a wide range of Industry 4.0 applications, such as building automation and smart manufacturing systems.

Working Principle

The ISL6402AIR-T is a low-noise and high PSRR 3.3V voltage regulator featuring both linear and switching modes. It is designed to operate at a fixed output voltage of 3.3V and switch between linear and switching modes depending on load current. When the load current is less than 5mA, the device will switch to a higher efficiency mode of operation. When the load current increases, the device will switch back to linear mode, ensuring optimal system performance. The device is also fully protected against over-current, over-temperature and under-voltage.
