Frequently Asked Questions
What control mode does the UCC2818DTR use?
The UCC2818DTR uses current-mode pulse width modulation (PWM) control for power factor correction. Current-mode control directly regulates the inductor current on a cycle-by-cycle basis, providing inherent overcurrent protection and faster transient response compared to voltage-mode PFC controllers.
What is the supply voltage range for the UCC2818DTR?
The UCC2818DTR operates from a supply voltage ranging from 10.3V minimum to 18V maximum, with a nominal operating voltage of 12V. This range is compatible with standard auxiliary supply rails derived from the power supply transformer, requiring no additional regulation for the controller bias supply.
What package does the UCC2818DTR come in?
The UCC2818DTR is housed in a 16-pin Small Outline IC (SOIC) package, designated PDSO-G16. This surface-mount package is widely used for power management ICs and supports standard SMT assembly processes, making it compatible with high-volume automated PCB manufacturing.
What is the primary function of the UCC2818DTR?
The UCC2818DTR is a power factor correction controller that shapes the AC input current drawn by a power supply to be sinusoidal and in phase with the AC input voltage. This improves the power factor toward unity, reducing reactive power and harmonic distortion to comply with international standards such as IEC 61000-3-2.
What applications are suitable for the UCC2818DTR?
The UCC2818DTR is suited for active PFC boost converter front-ends in AC-DC power supplies, server and telecom power units, variable speed motor drives, and industrial inverters. It is particularly valuable in designs that must comply with power factor and harmonic emissions standards required in commercial and industrial markets.
