The ICE2QR1080GXUMA1 switch mode power supply (SMPS) is a power management integrated circuit (PMIC) designed primarily for low power AC-DC conversion applications. It provides a wide range of features, such as adjustable output voltages, wide input voltage ranges, fast-start up times, low no-load operation, and advanced protection features. The integrated circuits have been optimized for small-to-medium sized AC-DC converters and are suitable for a wide range of applications in consumer, industrial, and automotive markets.

The ICE2QR1080GXUMA1 is a low power AC-DC converter with a voltage switch-mode power supply (SMPS) design. It is fully integrated and supports output current up to 1.6A. The ICE2QR1080GXUMA1 provides a reliable, cost-effective solution for a variety of low power applications. The integrated chipsets support input voltages ranging from 10.8V up to 20V, with output voltages ranging from 3.3V to 6V. Additionally, it provides advanced protection features such as current limit, over-temperature, and over-voltage protection.

The ICE2QR1080GXUMA1 is composed of several high-performance power electronics components. The core components of the device include an external MOSFET, gate driver, pulse-width modulation (PWM) controller, and flyback transformer. The external MOSFET helps regulate the voltage level, allowing for output voltages to be adjusted according to the requirements of the application. The gate driver, on the other hand, switches the MOSFET in order to control the output voltage. Furthermore, the PWM controller is responsible for generating a fixed frequency signal based on the input voltage and output current, while the flyback transformer helps to boost the output voltage.

The ICE2QR1080GXUMA1 works by converting the input AC voltage to a regulated DC voltage suitable for powering a microcontroller or a digital signal processor. The input AC voltage is rectified and then fed to a series of power switching devices that act as a buck regulator, creating a short duration output voltage pulse. The width of the pulse is modulated, allowing for the output voltage to be adjusted, so that it is suitable for the desired application.

The ICE2QR1080GXUMA1 is a highly integrated, low power AC-DC converter that provides excellent power conversion efficiency, which is achieved through increased power switching frequencies and optimized waveform control. Additionally, the device comes with advanced protection features such as over voltage, over temperature, and over current protection. As such, it is suitable for a wide range of applications in the consumer, industrial and automotive markets, making it an ideal solution for low power AC-DC conversion applications.
