PMIC - AC DC Converters, Offline Switchers

The ICE1HS01G1XUMA1 integrated circuit (IC) is part of a family of power conversion solutions offered by Infineon Technologies. It is designed for use in AC-DC power supply and offline switchers applications.

The ICE1HS01G1XUMA1 is an integrated circuit for offline switching applications and is mainly used for AC-DC conversions. It includes a buck converter circuit and a MCU control circuit. The buck converter provides an efficient way of converting AC to DC power. It can handle input voltages up to 600V and has an output current up to 1.5A. The MCU control circuit provides a programmable and flexible control method for the converter. The device also has a power line monitor (PLM) which monitors input line voltage and current, allowing it to detect signs of faults or damage to the input power lines.

The key feature of the ICE1HS01G1XUMA1 is its ability to operate in both open- and closed-loop modes. In open-loop mode, the converter operates under a fixed duty cycle and frequency. The control loop compensates for changes in the load by adjusting the duty cycle or frequency. In closed-loop mode, the converter operates with a fixed switching frequency, and the duty cycle is adjusted to maintain the output voltage at a constant level. This ensures stable and precise regulation of the output voltage and eliminates the need for complex output voltage regulation.

The ICE1HS01G1XUMA1 is suitable for a wide range of AC-DC power applications. These include power adapters, battery chargers and chargers for portable electronics. It is also suitable for other applications such as led lighting, and more. The device is also compliant with EMC and safety standards and has very good efficiency and power density, making it an ideal solution for many applications.

In summary, the ICE1HS01G1XUMA1 integrated circuit is a highly integrated and cost effective solution for AC-DC power supplies and offline switchers, providing high efficiency and flexibility. The device offers both open- and closed-loop control capabilities, allowing for precise and efficient control of output voltage. It offers compliance with EMC and safety standards and has a small form factor, making it suitable for a range of applications including power adapters, battery chargers and chargers for portable electronics.
