The L6562AN is a highly integrated and feature-rich Power Factor Correction (PFC) controller produced by STMicroelectronics. This advanced device is designed for use in a wide range of applications requiring power factor correction, such as switched-mode power supplies, lighting systems, and industrial power units.

Key Features

• Transition-Mode PFC Controller: The L6562AN operates in transition mode, also known as boundary mode or critical conduction mode, which provides an optimal compromise between switching losses and EMI.
• Low Harmonic Distortion: This controller is engineered to minimize total harmonic distortion (THD), thereby improving power quality and meeting stringent regulatory standards.
• High Efficiency: The device is optimized for high efficiency, reducing energy consumption and heat generation in applications.
• Low Quiescent Current: It features a very low quiescent current, which is beneficial for achieving low power consumption during standby or no-load conditions.
• Adjustable Output Overvoltage Protection: The L6562AN includes an adjustable output overvoltage protection feature, safeguarding the system against voltage spikes and surges.

Applications

The versatility of the L6562AN makes it suitable for a variety of applications, including:

• AC-DC Adapters
• Power Supplies for LCD TVs and Monitors
• Power Supplies for LED Lighting
• Offline Power Supplies for Servers and Telecom Systems

Technical Specifications

The L6562AN features a wide supply voltage range and is housed in a compact, surface-mount package. Its technical specifications include:

• Supply Voltage Range: 11.4 V to 18 V
• Operating Frequency: Up to 200 kHz
