The L6562ADTR from STMicroelectronics is a state-of-the-art Transition-Mode PFC (Power Factor Correction) controller, operating in Transition Mode (TM). It is part of ST's power management integrated circuit portfolio and is specifically designed to build robust and compact PFC stages. This device is suitable for a wide range of applications, including those that require improved energy efficiency and reduced power consumption, such as switch-mode power supplies, lighting systems, and adapters.

Key Features

• Transition-Mode Control: The L6562ADTR operates in Transition Mode, offering an optimal compromise between system efficiency and simplicity for power levels up to a few hundred watts.
• Real-Time Overcurrent Protection: It includes an effective two-level overcurrent protection that enhances system reliability, preventing damage from overload conditions.
• Low Standby Power Consumption: The quiescent current is very low, which makes the L6562ADTR an excellent choice for applications with stringent energy saving requirements.
• High-Voltage Startup: This feature allows the device to self-supply directly from the rectified mains, leading to a simplified power supply design and reduced system cost.
• Multi-Purpose Current Sense: The L6562ADTR features a current sense pin that serves for both overcurrent protection and feedback for the output regulation loop.
