Introducing the UCC28061 from Texas Instruments

The UCC28061 is a robust and innovative power management integrated circuit designed by Texas Instruments, specifically engineered for the efficient control of power factor correction (PFC) circuits. This advanced IC is tailored to meet the needs of a variety of applications, particularly those requiring a power factor close to unity, such as in switch-mode power supplies (SMPS) used in desktop computers, televisions, and other consumer electronic devices.

At the heart of the UCC28061 lies its unique Natural Interleaving™ technology, which ensures automatic phase shedding and rapid response times. This feature helps to optimize performance by reducing total harmonic distortion and improving the efficiency of the power supply, even under light-load conditions. The result is an increase in energy savings and a reduction in power-related emissions, making the UCC28061 a choice component for eco-conscious designs.

One of the key advantages of the UCC28061 is its ability to operate in a transition mode, also known as critical conduction mode (CrM), which further enhances efficiency by minimizing switching losses. The integrated circuit is designed to support a wide range of input voltages, making it a versatile solution for global applications. Its built-in soft-start feature ensures a smooth power-up process, thereby reducing stress on the system and extending the lifespan of the end product.

The UCC28061 also boasts a suite of protection features, including over-voltage, under-voltage, and over-current protection, which safeguard the system against potential damage caused by electrical anomalies. Its frequency dithering capability helps to minimize electromagnetic interference (EMI), ensuring compliance with international EMI standards.

For designers and engineers seeking to enhance the efficiency and reliability of their PFC designs, the UCC28061 from Texas Instruments offers a compelling solution. Its combination of advanced control features, protection mechanisms, and compliance with global energy standards makes it an ideal choice for powering the next generation of electronic devices.
