The UCC2813D-4G4 is an AC/DC converter and offline switcher used in a variety of applications. This device works by converting incoming AC current into a regulated DC output, or vice versa. Eligible applications for the UCC2813D-4G4 include but are not limited to lighting installations, telecom equipment, UPSs, and industrial motors.

The Universal Serial Bus (USB) interface controller used in the UCC2813D-4G4 allows for flexible and efficient control of the device, as well as enhanced usability. The integrated data-interface enables communication with the device over a wide range of baud rate options. Additionally, the device is also backward compatible with all previously released UCC2813 products.

The UCC2813D-4G4 features a maximum switching frequency of 500kHz, an operating range of -50 to +60C, and a power supply of up to 125W. As such, the device can handle most applications with ease. It also meets the accepted standards of EN55014-1 and EN55014-2 and the RoHs Directive.

The device’s built-in voltage loop enables it to maintain steady output voltage and current, even during load transients. This ensures that the device delivers a reliable and consistent output, reducing energy wastage and the need for frequent system reboots due to faulty devices. It also features a wide range of selectable protection features designed to protect against over-temperature, over-current, and short circuit.

The working principle of the UCC2813D-4G4 is based on a synchronous buck-boost topology. The device includes two stages of power conversion, both of which are achieved using high-frequency switching elements. The device is also equipped with a feedback network, which enables a sensed output voltage and current to be fed back to the control circuitry. This feedback process allows for a full-scale setpointValue regulation and management of the output signal.

In summary, the UCC2813D-4G4 is a versatile AC/DC converter and offline switcher designed for various applications. It features an integrated USB interface controller, as well as a range of protection features designed to protect against over-temperature, over-current, and short circuit. Also, it is based on a synchronous buck-boost topology, which enables efficient and stable performance. As such, it is an excellent choice for applications requiring reliable and efficient DC power conversion.
