ICE5AR4770AGXUMA1

PMIC - AC DC Converters, Offline Switchers

The ICE5AR4770AGXUMA1 is an integrated circuit for power management. It is primarily used in industry applications such as motor control, solar power inverters, LED lighting, automotive, and consumer applications. It is a non-isolated, single-stage AC-to-DC converter with active rectification, switchmode, and overload protection functions. It supports a wide voltage range from 10 V to 60 V and provides open loop current mode control. It contains a superior number of integrated features which enable it to adapt to different application requirements quickly.

On one hand, the ICE5AR4770AGXUMA1 offers a complete set of functions and features including low start-up current, wide input voltage range, integrated soft start, current mode control, protection features and single or multiple outputs. On the other hand, it also offers a complete range of safety features such as over-current, over-voltage, over-temperature, and under-voltage lockout to protect the internal circuits of the device.

The operating principle of the ICE5AR4770AGXUMA1 is based on a flyback topology. The main feature of a flyback topology is that it enables the device to store energy from the input source and then the device release it as needed, making it a highly efficient power converter. The power switch (transistor) of the ICE5AR4770AGXUMA1 is a MOSFET which is integrated in the chip. This MOSFET is controlled by an integrated driver, which is then controlled by a closed loop control loop that adjusts the duty cycle of the MOSFET and hence the output voltage of the converter.

The ICE5AR4770AGXUMA1 also has an overload protection circuit which protects the components from high or too low voltage or current spikes. The main advantage of the ICE5AR4770AGXUMA1 is that it combines all the features of an AC to DC converter in one package, it is compact, and can handle a wide range of input voltage. This makes it suitable for applications such as motor control, solar inverters, LED lighting, and automotive, among others.
