The UCC28C42P is a PWM Controlled Off-Line Switcher series, manufactured by Texas Instruments. It is an integrated AC/DC converter comprising a single-stage buck power factor corrector (PFC) and a single-stage half bridge quasi-resonant flyback. This type of converter is widely used in both offline and distributed power applications, including small form factor gaming and industrial PCs as well as flat panel displays.

This series of integrated converters offers a number of features, such as peak current mode control, valley current limit, programmable reference voltage, adjustable output current limit and input voltage mode control, that together ensure reliable and robust operation. The UCC28C42P also includes a suite of protections, such as an overvoltage protector, undervoltage lock-out, and an overtemperature detector.

In terms of applications, the UCC28C42P is suitable for powering a wide range of AC/DC converters. It can be used for low-voltage, medium-voltage, and high-voltage isolated AC/DC converters, as well as for multiple output DC-DC converters. It is also suitable for powering LED lighting and other AC/DC power systems.

The working principle of the UCC28C42P is based on the concept of pulse-width modulation (PWM). Controlling the duty cycle of the pulse, or pulse width, is an effective way of controlling the output voltage and current. In the UCC28C42P, the pulse width is controlled by a PWM comparator, which compares the input voltage on the upper output of the error amplifier to the sawtooth waveform. As the external voltage increases, the PWM comparator increases the pulse width, thus increasing the output current.

In addition, the UCC28C42P comes with a number of features such as valley current limit, programmable reference voltage, adjustable output current limit, and input voltage mode control. These ensure that the converter operates reliably and achieves the required output voltage levels. In addition, the presence of the overvoltage protector, undervoltage lock-out, and overtemperature detector protect the converter from damage and unwanted operation.

Overall, the UCC28C42P offers a compact, efficient, and reliable solution for powering AC/DC converters. Its integrated features make it an ideal choice for applications that require a robust, reliable, and efficient power supply. It is suitable for a variety of AC/DC converters, including low-voltage, medium-voltage, and high-voltage isolated AC/DC converters, as well as for multiple output DC-DC converters. The PWM control ensures that the converter is able to efficiently produce the required output voltage and current levels, while the suite of safety features protect the entire system from damage or unwanted operation.
