ON Semiconductor MC33067PG Product Overview

The MC33067PG is a high-performance, resonant mode controller designed by ON Semiconductor, tailored for efficient and reliable operation in power supply applications. This integrated circuit (IC) is engineered to provide precise control in full-bridge or half-bridge resonant mode power supplies, which are often used in applications requiring high efficiency, such as in telecommunication equipment, servers, and high-density power converters.

The MC33067PG incorporates a range of features to enhance the performance of resonant mode power supplies. One of its key attributes is the ability to self-oscillate at a frequency determined by an external tank circuit, which consists of the resonant inductor and capacitors. This self-oscillation feature helps to simplify the circuit design and reduce the number of external components required, resulting in a more compact and cost-effective power supply solution.

Additionally, the device offers built-in protection mechanisms, such as overcurrent protection and fault protection, to safeguard the power supply and the end application from potential damage. These protections ensure that the power supply operates within safe parameters, enhancing the reliability and longevity of both the power supply and the application it powers.

The MC33067PG is also capable of zero voltage switching (ZVS), which minimizes switching losses and improves overall efficiency. This feature is particularly beneficial in reducing the thermal stress on components, thereby extending the operational life of the power supply.

ON Semiconductor has packaged the MC33067PG in a 16-pin PDIP (Plastic Dual-In-Line Package), which is widely used and easily integrated into various circuit board layouts. The package is designed for through-hole mounting, providing a robust mechanical and electrical connection.

In summary, the MC33067PG resonant mode controller from ON Semiconductor offers a blend of high performance, efficiency, and reliability for advanced power supply designs. Its integrated features and protections, coupled with the ease of integration, make it an excellent choice for designers looking to optimize their power supply solutions.
