ML4812IQ Description

The ML4812IQ is a Power Factor Correction (PFC) controller designed for critical conduction mode (CRM) applications. Manufactured by onsemi, this IC is part of the Power Management Integrated Circuit (PMIC) category, offering efficient power conversion and control. The ML4812IQ operates within a supply voltage range of 12V to 18V and features a startup current of 800 µA, ensuring minimal power consumption during startup. It is packaged in a tube format, suitable for surface-mount applications, and is classified under HTSUS code 8542.39.0001. The product is REACH unaffected and has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited exposure to moisture. However, it is important to note that the ML4812IQ is currently in an obsolete product status, meaning it is no longer in active production.

ML4812IQ Features

The ML4812IQ offers several unique features that set it apart from similar PFC controllers. Its critical conduction mode (CRM) operation ensures high efficiency across a wide range of load conditions. The low startup current of 800 µA minimizes power consumption during the initial power-up phase, making it ideal for energy-sensitive applications. The surface-mount package type allows for easy integration into compact designs, while the tube packaging ensures reliable handling and storage. The ML4812IQ's compliance with REACH regulations and its MSL 1 rating make it suitable for use in various industrial and consumer electronics environments. Additionally, the 12V to 18V supply voltage range provides flexibility in power supply design.
