Frequently Asked Questions
What switching frequency range does the UCC28180DR-P support?
The UCC28180DR-P supports a switching frequency range from 18 kHz to 250 kHz, allowing designers to optimize between switching losses and magnetic component size in CCM PFC converter designs.
Which power supply designs benefit most from the UCC28180DR-P's enhanced transient response?
Server and telecom power supplies operating above 300 W benefit most from the enhanced start-up and transient response. The controller maintains output regulation within tight voltage bands during sudden load steps, ensuring stable 400 V DC bus operation.
How does the UCC28180DR-P achieve low total harmonic distortion in AC/DC converters?
The UCC28180DR-P uses feed-forward line voltage compensation to shape the inductor current to follow the sinusoidal input voltage. This technique reduces THD below 5% at full load, meeting IEC 61000-3-2 harmonic limits for equipment above 600 W.
What protection features are built into the UCC28180DR-P?
The UCC28180DR-P includes integrated overvoltage protection, overcurrent protection, and soft-start control. These features protect the 400 V output bus and downstream circuitry from fault conditions, improving system reliability in 24/7 industrial applications.
