Power Factor Correction (PFC) is utilized by engineers in the design of AC-DC power supplies and DC-DC converters to increase the efficiency of their designs. It is a technique used to reduce the power wasted in an AC-DC power supply and increase the overall efficiency of the entire system.

The IR11452STRPBF is a power factor correction (PFC) controller IC used for offline flyback topology. It is specifically designed to control medium power flyback AC-DC converters with low power factor rate. It operates in a critical conduction mode (CRM) or Power Factor Correction (PFC) regimes and can make power factor reaching > 0.95. The operating temperature range is –40°C to +85°C with short circulation protection, power don protection and over voltage protection. It is also designed with phase-shifted soft-switching technology to reduce the switching losses and save energy.

The main objective of this IC is to reduce the reactive power losses in AC-DC power supplies and DC-DC converters. Utilizing the critical conduction mode (CRM), PFC helps to reduce the harmonic current injected into the AC source and improve system efficiency to meet industry specific power quality standards. With its built-in protection circuits and overload protection, the IR11452STRPBF can eliminates the risk of damage from abnormal operating conditions and provides a safe and reliable device for system stabilization.

The IR11452STRPBF operates in a voltage-mode control, providing a stable output voltage for the system. This voltage-mode control uses a feedback loop to provide a stable output voltage by constantly monitoring the output of a linear and non-linear load. This voltage is compared to an internal voltage reference to generate a closed-loop control signal. The control signal then adjusts the switching of the MOSFETs to maintain a regulated output voltage.

The IR11452STRPBF also has an adjustable output voltage as well as an over voltage protection and under voltage protection. When an over-voltage or under-voltage situation occurs, the controller stops the PFC process and disables the power stage. This protects the system from power loss and improves the overall system stability.

The IR11452STRPBF is a very versatile IC and can be used in a wide range of applications, from computer power supplies and industrial equipment, to automotive and consumer electronics systems. Its feature set and ease of use make it a great choice for designers looking for a reliable and efficient PFC solution.
