Applications
The UCC2819ADG4 is designed for active power factor correction (PFC) in AC-DC power supplies used in desktop computers, industrial equipment, and consumer electronics. Its current-mode PWM control technique minimizes harmonic distortion on the AC mains, helping designs meet IEC 61000-3-2 harmonic emission standards. It is also suitable for telecom power supplies, motor drives, and uninterruptible power supplies (UPS) requiring high power factor and efficient energy conversion.

Frequently Asked Questions
What is the switching frequency of the UCC2819ADG4?
The UCC2819ADG4 supports switching frequencies up to 115kHz, enabling the use of smaller passive components such as inductors and capacitors in the power factor correction boost stage, which reduces overall system size and cost.
What is the input voltage range for the UCC2819ADG4?
The UCC2819ADG4 operates with an input voltage range of 10.8V to 17V, with a nominal voltage of 12V. This range is compatible with standard 12V auxiliary power rails commonly found in ATX and industrial power supply designs.
What control technique does the UCC2819ADG4 use?
The UCC2819ADG4 uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, improved transient response, and simplified compensation compared to voltage-mode control.
What package is the UCC2819ADG4 available in?
The UCC2819ADG4 is available in a 16-pin SOIC (Small Outline Integrated Circuit) package, a standard surface-mount package widely used in power management ICs that provides good thermal performance and easy soldering.
