ICE2QR0665ZXKLA1

The ICE2QR0665ZXKLA1 is a PMIC (Power Management Integrated Circuit) AC/DC converter, with an offline switcher. It is used where AC or DC power needs to be converted from a low-voltage input to higher-voltage output, or vice-versa.

The ICE2QR0665ZXKLA1 supports wide output voltage range between 18V to 36V. It features a number of protection and monitoring functions, including over-voltage protection (OVP) and open loop protection (OLP). It also includes an internal voltage regulator, and the ability to adjust the output voltage by a single external reference pin without the need to use an external control circuit.

The ICE2QR0665ZXKLA1 is capable of providing up to 6A of load current, with typical startup and line transient performance. The IC implements the Zero Voltage Switching (ZVS) with light load efficiency of 70%. It offers wide operating frequency range of 100KHz to 500KHz, offering efficient operation.

The device offers a number of features for safeguarding the circuit against potential damages, including output current limit, temperature protection, frequency foldback, UVLO, and adjustable soft start. It also includes an internal thermal shutdown circuit to protect the IC from thermal overstress.

The ICE2QR0665ZXKLA1 is suitable for a variety of applications, including industrial motor controls, appliance motor drive circuits, battery-powered equipment, AC-DC power supplies and mobile phones. It is also used in a variety of fields, such as lighting, communications systems, measuring instruments, and automotive electronics.

The IC operates by providing a high-frequency CMOS oscillator signal that drives the power supply\'s switches on and off. When power is applied, the oscillator signal causes the switches to turn on and off, producing an AC current that is rectified and filtered into DC output. The output voltage is regulated by controlling the amount of time each switch is on and off. The input voltage is sensed and compared to the output voltage reference, and the switch times are varied accordingly.

The ICE2QR0665ZXKLA1 is a reliable and robust AC/DC converter designed for a wide range of applications. With its wide voltage range, integrated protection and monitoring functions, and wide operating frequency, the IC is suitable for a variety of applications, such as industrial motor controls, appliance motor drive circuits, battery-powered equipment, AC-DC power supplies, and mobile phones.
