The UCC3819APW is a PFC controller from Texas Instruments that doubles as a current mode controller for switch-mode power supplies. It is designed to offer high performance and low cost solutions for systems requiring high power conversion efficiency.
It features an adjustable height picofarad programmable gain boost circuitry and an adjustable output current limit. This makes it an ideal PFC controller for systems that require high conversion efficiency and low cost solutions.
The working principle of the UCC3819APW controller is to adjust the DC-link voltage to the desired voltage level during AC input variations. This is done through the use of the feedback voltage from a voltage-mode converter. The higher the DC-link voltage, the better the controller performance.
The main application field of the UCC3819APW is for battery chargers, power inverters, Uninterruptible Power Supplies (UPS) and charge pump converters for DC-DC power supplies. It is also used for very high power switched mode power supplies, low power auxiliary power supplies used in a variety of applications. The controller is also integrated in automotive systems including Battery Charge Systems, Advanced Power Supply Controllers and Variable Frequency Power Supplies.
The UCC3819APW has many advantages compared to other PFC controllers. It features fast current mode control of the normal average waveform, which is necessary for a reliable power factor correction. This form of control reduces the output ripple amount. Its high gain, programmable voltage input and output enable easy design and modularity.
The UCC3819APW also features protection from input voltage overshoots by limiting the inrush current, protection from over-voltage and over-current conditions, an internal temperature monitor, and adjustable output current limit. In addition, its low standby power consumption helps conserve energy.
Overall, the UCC3819APW is a highly versatile and efficient PFC (Power Factor Correction) controller designed for battery chargers, power inverters, UPS and other switch-mode power supplies. It is highly efficient and cost-effective, making it an ideal solution for applications requiring high power conversion efficiency.
