Power Factor Correction (PFC) refers to the process of improving the power factor of an ac power supply. In an electric system, power factor is the ratio between a real power, which generally drives the load, and the total apparent power drawn by the load. A low power factor can be caused by the presence of reactive elements in the circuit, such as inductive loads and capacitive loads. PFC, through the use of specialized electrical components, is used to increase the power factor of the circuit and reduce the level of reactive elements.PMIC - PFC (Power Factor Correction) devices are semiconductor-based components used in switching power supplies and ac/dc converters to improve the power factor of such circuits. A typical application for a PFC device is the switching power supply for a computer or other electronic device, where the need for efficient operation is paramount.The TEA19162HT/1J is a PMIC - PFC (Power Factor Correction) controller designed for use in synchronous rectifier applications. It is based on ON Semiconductor’s proven charge-pump PFC control technology and was designed to offer high efficiency, low EMI and low component count at a competitive cost. The device uses an optimized control loop to reduce peak inductor current ripple and to provide stable output voltage, including well-controlled startup. The device also has integrated system protection such as input/output overvoltage and overcurrent protection, as well as thermal protection.In a typical application, the TEA19162HT/1J is used to control a boost converter based converter topology that is used to convert a sinusoidal input voltage to an AC output voltage with a higher power factor. The device controls the voltage across the switch by comparing the output voltage to an internal reference voltage and using this information to adjust the duty cycle of the switch. The control loop also contains a slope compensation circuit to control the slew rate of the output voltage in order to reduce the inductor current ripple.The TEA19162HT/1J also includes additional features that help improve system efficiency and performance. These include an integrated DC output voltage sensing circuit that eliminates the need for an optocoupler and improves overall system efficiency. It also has an integrated dead time generator that eliminates the need for an external component. The device also has integrated undervoltage lockout and overcurrent protection.The TEA19162HT/1J is ideal for applications with power ranging from 4W to 75W. It is available in an 8-pin SOIC package and can be used in a wide range of switch mode power supplies, including off-line, telecom and ac/dc converters.Overall, the TEA19162HT/1J PMIC - PFC (Power Factor Correction) controller provides a high performance, cost effective solution for improving the power factor of switching power supplies and ac/dc converters. Its integrated features also provide system designers with a simpler, more efficient solution that reduces total system costs.
