<h2>E-L6565D Application Field and Working Principle</h2><h3>Introduction</h3>The E-L6565D is a single-channel synchronous rectifier controller dedicated to offline AC/DC converters and offline switchers. It is compatible with popular modern architectures and comes with a wide array of features and performance enhancing options. In this article, we will look into the application field and the working principle of the E-L6565D in detail.<h3>Application Field</h3>The E-L6565D is mainly used in AC/DC converters and offline switchers. It has a wide range of applications, including lighting systems, power supplies for automotive and home appliances, cellphone phones, and more.The E-L6565D is a highly efficient solution for AC/DC converters and offline switchers, offering high output power, improved thermal performance and more. The device is designed for high-voltage operation and is capable of operating from a wide input voltage range of 7V to 300V.The E-L6565D also offers a wide range of features and performance enhancing options, such as built-in start up, output voltage control, soft start, over-current protection, over-voltage protection, over-voltage lockout, and over-temperature protection.The device is also compatible with a variety of popular modern architectures, such as PoE, USB Power Delivery, and PMBus, making it an ideal choice for many diverse applications.<h3>Working Principle</h3>The E-L6565D is a synchronous rectifier controller that controls the flow of current through the load. It combines the energy gained from the rectified alternating current with that from the DC voltage source to produce a combined, steady DC voltage.The device operates by sensing the voltage across the load and adjusts the duty cycle of the rectifier in order to ensure that the load receives a regulated DC voltage. The device also uses a resonant circuit to ensure that alternating current is correctly converted into a steady DC voltage and has a wide input voltage range, making it suitable for a variety of applications.The device has two operating modes, and these include the “Power Mode” and the “Track-Mode”. The Power Mode is used when the load is receiving a predetermined output voltage and the Track-Mode is used when the load is receiving a fluctuating input voltage.The rectified alternating current passes through four circuit stages, including the Bridge Rectifier, the Soft Start stage, the Resonant stage, and the Controller stage. The output voltage of the controller is monitored by an integrated feedback control loop, and this helps ensure that the load receives a steady DC voltage.<h3>Conclusion</h3>The E-L6565D is a single-channel synchronous rectifier controller dedicated to offline AC/DC converters and offline switchers. The device is highly efficient, capable of operating from a wide input voltage range of 7V to 300V and offers a wide range of features and performance enhancing options. The device also has two operating modes and uses a resonant circuit to ensure that alternating current is correctly converted into steady DC voltage.
