The L6561D013TR is an Integrated Circuit (IC) component manufactured by STMicroelectronics. It is a versatile and high-performance power factor correction (PFC) controller specifically designed for SMPS (Switched-Mode Power Supply) applications. This IC offers several key features that make it ideal for power factor correction circuits.
One of the prominent features of the L6561D013TR is its ability to achieve near-unity power factor correction in power supplies. By regulating the input current to follow the mains voltage waveform, it ensures that the power factor remains close to 1 by correcting the phase and amplitude errors between the input voltage and current.
This IC operates in the Critical Conduction Mode (CRM), making it suitable for single-stage PFC topologies. It employs voltage mode control, ensuring stable and accurate regulation of the power supply output voltage while maintaining a high power factor.
The L6561D013TR supports universal input voltage ranges and is capable of handling a wide range of input voltages (85VAC to 265VAC). This characteristic makes it an excellent choice for applications where power supplies need to work with different voltage standards worldwide.
Another essential feature of this IC is its capability of delivering high efficiency over a wide load range. It achieves this through its burst mode operation at no load or light load conditions, improving overall energy efficiency and reducing power consumption.
