The MC33364D2G is an integrated circuit within the Power Management and Control family developed by ON Semiconductor for for AC-DC Converters, Offline Switchers, and other related applications. ON Semiconductor is a semiconductor manufacturing and designing organization that has been in operation since 1999. The ON Semiconductor family of products is designed with modern functions, power management, and control technologies.The MC33364D2G is designed to provide a comprehensive range of features for various AC-DC, offline switcher applications. It consists of one or more high voltage MOSFETs, two low voltage MOSFETs, bilateral gate logic, and gate drive circuit with a regulated output voltage. The device supports a variety of control algorithms such as burst mode, variable frequency, linear current mode, and constant voltage.The MC33364D2G is perfect for applications that require high output power with high efficiency, low power losses, fast transient response, and low cost. Its applications include LED lighting, automotive, renewable energy, industrial, elevator/escalator/motor drive systems, smart appliances, and more.The MC33364D2G is unique because of its capability to provide a single-stage closed loop control system with a voltage-mode control (mode); power efficiency and accuracy; and its flexibility to be used for different primary-side control schemes thereby eliminating the need for an opto-coupler. It also features a high switching frequency of 400kHz, allowing for high-speed current mode pulsewidth modulation.The device operates by sensing the output power of the primary side switching MOSFET during the soft-start sequence, and providing direct feedback via the MOSFET\'s drain-source voltage. During standard operation, the drain-source voltage of the high-side MOSFET is sensed directly, while the voltage of the low-side MOSFET is sensed by an auxiliary current path. A compensation network and the internal oscillator allow for a controlled, fast turn-on and turn-off of the switching MOSFETs to ensure that the desired output voltage is maintained.In summary, the MC33364D2G is a power management and control device that is specifically designed for AC-DC converter and other offline switcher applications. It provides a comprehensive set of features and high performance levels, enabling it to meet the needs of many applications requiring high output power, efficiency, accuracy, and low power losses. It offers a single-stage closed-loop control system, high switching frequency, and the flexibility to configure it for different primary-side control schemes with or without an opto-coupler. Therefore, it is the perfect solution for many low-end applications such as LED lighting and smart appliances requiring high output power and efficiency.
