Power management integrated circuits (PMICs) are important components of modern electronics and industrial systems. They are used to provide power conversion and regulation functionality in a wide range of applications. There are many types of PMICs, including AC-DC converters, offline switchers, DC-DC converters, and linear regulators. Each type of PMIC has its own particular characteristics, advantages and limitations.

The ICE2BS01 is a high performance offline switcher from Infineon Technologies that is designed for power conversion and regulation applications. The device provides high efficiency and low power consumption. It offers a wide input range of 85 to 265 Vac and a wide output range of 1.2 to 5.0 VDC. This makes it suitable for various applications, such as white goods, computer peripheral, audio system, lighting and industrial control.

Working Principle

The ICE2BS01 offline switcher uses a self-driven continuous conduction mode PWM technique. The Flyback regulator section consists of a primary switch, secondary switch and a feedback control circuit. When the power supply is off, energizing the auto-restart bypass which bypasses the start-up circuity. When the power supply is on, the start-up circuity is enabled and the device is ready to work.

In normal operating mode, a high voltage flyback transfer is generated. The primary switch is switched on and a current is generated while the secondary switch is off. After a fixed time period, the primary switch is switched off and the current is cut off. At the same time, the secondary switch is activated and a the energy stored in the transformer is discharged.

The device also features an internal soft start, which prevents overloading of the power source during start up. The output voltage of the device is regulated by a constant-current limit control. The device also features short-circuit protection, over-temperature protection and over-voltage protection.

Application Fields

The ICE2BS01 is suitable for a wide range of applications, including remote control systems, air conditioners, refrigerators and washing machines, computer peripheral devices, audio equipment and lighting systems. The device is also suitable for industrial control systems, such as industrial motion control and process control systems. The high efficiency and low power consumption make the device suitable for power-sensitive applications where energy savings are essential.

In addition, the device is also suitable for automotive applications. For example, it can be used in fuel-injection systems and airbag systems. With its high efficiency, low standby power and wide operating temperature range, the device is ideal for automotive applications where reliability and performance are paramount.

Conclusion

The ICE2BS01 is a highly efficient offline switcher from Infineon Technologies that is designed for power conversion and regulation applications. The device delivers high efficiency and low power consumption. It features an internal soft start, over-voltage protection and over-temperature protection. The device can be used in a wide range of applications, including household appliances, industrial control systems and automotive applications.
