Power Factor Correction (PFC) is an important part of Power Management Integrated Circuits (PMICs). It regulates the voltage and current in electronic circuits, enabling them to operate reliably and efficiently over a range of load conditions and operating voltages. UCC28180DR is a PMIC with PFC that provides accurate and efficient power factor correction, offering real-time feedback and control to ensure the power supply system remains compliant with global standards.
The UCC28180DR is a transistor-switched PFC with a synchronous rectification output capable of working with AC power sources from 85VAC to 305VAC, covering a wide range of applications and line voltages. It employs a two-stage approach, consisting of a main voltage regulator that ensures the output voltage is under control, and a bridge rectifier stage that eliminates input current harmonic distortion. By reducing current harmonics, it reduces power losses and improves power quality. It also has an in-built voltage-mode controller to ensure fast and accurate output voltage regulation.
The UCC28180DR operates with a fixed frequency of 100 kHz and employs a peak current-mode control scheme. This scheme allows the power factor correction to be applied to both capacitive and inductive loads simultaneously, thereby reducing input power consumption. It also prevents up to 0.5% undershoot, ensuring a clean output voltage waveform. Furthermore, the device supplies higher output power than comparable discrete solutions and comes with an integrated bootstrap diodes which eliminates the need for additional components.
The UCC28180DR also includes protection features such as undervoltage lockout, overvoltage protection, and over-temperature protection supported by LED status indicators. It operates over a wide temperature range, from –40°C to +105°C and is integrated with a slew-rate control preventing high EMI levels from being generated.
The UCC28180DR is ideal for applications such as motor inverts, industrial lighting, wind and solar power systems, telecom infrastructure, and automation systems which require high efficiency and power factor correction capabilities. It is well-suited for a variety of markets and applications as it offers cost-effectiveness and reliability.
