The L6562ATDTR from STMicroelectronics is a state-of-the-art transition-mode Power Factor Correction (PFC) controller, designed for driving PFC pre-regulators. This highly integrated IC enables the development of compact and efficient power supplies, which are compliant with the most stringent energy-saving regulations.

Equipped with STMicroelectronics' proprietary MultiMode™ control, the L6562ATDTR allows for a seamless transition between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM), optimizing efficiency over a wide range of load conditions. This adaptability ensures that power supplies can maintain a high power factor and low THD (Total Harmonic Distortion) across varying levels of power demand.

The device comes in a compact SO-8 package, making it an ideal choice for space-constrained applications. It supports a wide range of input voltages, making it versatile for various global power standards. The L6562ATDTR is also equipped with a host of protection features, including over-voltage protection, under-voltage lockout, and over-current protection, which safeguard the power supply and the end equipment against a myriad of electrical anomalies.

Key features of the L6562ATDTR include an output overvoltage protection that prevents runaway output voltages, not requiring an auxiliary winding. It also boasts very low operating quiescent current and a low (

Whether it's for consumer electronics, such as TVs and PCs, or industrial applications, the L6562ATDTR provides a reliable and efficient solution for power factor correction. Its robust design and advanced features make it an excellent choice for engineers looking to enhance the performance of their power supply designs while meeting environmental standards and reducing energy consumption.
