Frequently Asked Questions
What is the UCC28019D and what topology does it support?
The UCC28019D is a continuous conduction mode (CCM) PFC controller from Texas Instruments designed for boost converter topologies. It shapes the AC input current to be sinusoidal and in phase with the line voltage, achieving power factor values greater than 0.99 across a universal input range of 85V to 265V AC.
What is the maximum switching frequency of the UCC28019D?
The UCC28019D supports an adjustable switching frequency up to 600kHz, set by an external resistor connected to the RT pin. Typical designs operate between 65kHz and 200kHz to balance switching losses and magnetics size for the target power level.
What package does the UCC28019D come in?
The UCC28019D is available in an 8-pin SOIC (SO-8) package, which is a standard surface-mount package measuring approximately 5mm x 4mm. This compact footprint is well-suited for mid-power SMPS designs where board space is a consideration.
What are the key protection features of the UCC28019D?
The UCC28019D includes overvoltage protection (OVP), overcurrent protection (OCP), zero-cross detection for AC line synchronization, and a soft-start function to limit inrush current during startup. These protections help ensure robust and reliable operation in demanding industrial and consumer power supply applications.
What are common applications for the UCC28019D?
Common applications include front-end PFC stages in server power supplies, telecom rectifiers, industrial AC-DC SMPS, LED lighting drivers, and motor drive systems. It is particularly suitable for designs requiring compliance with harmonic current standards such as IEC 61000-3-2 at power levels from 100W to over 1kW.
