The UCC28083PWR is a popular integrated Circuit (IC) belonging to a family of advanced power management ICs designed for offline AC-DC converters and offline switchers. Widely used by companies in various applications, this device is an ideal drive IC for continuous conduction mode (CCM) resonant converters and single-stage CCM boost converters.

This IC takes the input directly from the mains AC and generates a DC output voltage. This combination of features makes it the perfect device for AC-DC power conversion in light control circuits, solar power applications and many others.

The UCC28083PWRis a CMOS-based integrated circuit that contains all the necessary functions to drive a current-fed load. It includes two differential amplifiers to buffer the input voltage, a high current switch, a synchronous rectifier, a flyback reset circuit, and a control system with several operational modes.

The UCC28083PWR provides a complete and efficient solution for high-power LED lighting, LED lighting management and dimming, LED backlighting, low-voltage DC-DC converters and AC-DC brick or offline converters.

The device works by using a high-current switch, such as a MOSFET, to supply current to the load. The switch is either controlled by a variable-frequency oscillator or a current-mode controller. The IC monitors the input voltage and the output current and adjusts the frequency of the oscillator or the duty cycle of the controller so that the output is maintained constant.

In addition, the UCC28083PWR can operate in several operating modes that can be used to adapt it to different applications. These operating modes include continuous conduction mode, discontinuous conduction mode, burst mode, pulse-skipping mode and voltage-mode control. Each of these modes has different advantages and can be used to optimize the performance of the AC-DC converter or switchers.

The UCC28083PWR is an ideal choice for applications requiring high performance and efficiency. It offers low power consumption, low electromagnetic interference (EMI) and excellent reliability. As a result, the UCC28083PWR is ideal for a wide range of applications including lighting, appliances, consumer electronics and the automotive sector.
