The UCC28063DR from Texas Instruments is a Natural Interleaving™ Transition-Mode PFC Controller with improved audible noise immunity. This IC is designed for applications requiring efficient power factor correction.
Key electrical specifications include an operating voltage range of 14V to 21V and a low operating current of 100 µA. The controller operates in discontinuous (transition) mode with a maximum duty cycle of 99%. It also features integrated 1A source/1.8A sink gate drivers.
The device is housed in a 16-SOIC package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C, ensuring reliable performance in various environmental conditions. Features like input filter and output capacitor ripple-current cancellation contribute to higher system reliability and smaller bulk capacitors, while advanced audible noise performance enhances user experience.
This PFC controller simplifies board layout and improves efficiency through sensorless current-shaping. It offers fail-safe Overvoltage Protection (OVP) with dual paths and inrush-safe current limiting to prevent MOSFET conduction during inrush, enabling the use of low-cost diodes without extensive snubber circuitry.
