Power Factor Correction ICs

L6563S Description

The L6563S from STMicroelectronics is a transition-mode Power Factor Correction (PFC) controller IC, designed for high-efficiency AC-DC power supplies. Operating in discontinuous conduction mode (DCM), it ensures compliance with stringent power quality standards while optimizing energy efficiency. With a supply voltage range of 10.3V to 22.5V and an ultra-low startup current of 90 µA, it minimizes standby power consumption. Packaged in a 14-pin SOIC (Surface Mount), it is RoHS3 compliant and suitable for industrial and consumer applications requiring compact, reliable PFC solutions.

L6563S Features

• Transition-Mode PFC Operation: Ensures near-unity power factor and low THD (Total Harmonic Distortion).
• Wide Supply Range (10.3V–22.5V): Supports flexible design integration.
• Low Startup Current (90 µA): Reduces power losses during standby.
• Surface-Mount (SOIC-14) Package: Ideal for space-constrained PCB designs.
• Active Clamp & Overvoltage Protection: Enhances system reliability.
• RoHS3 & REACH Compliant: Meets global environmental standards.
• MSL3 (168 Hours): Ensures moisture sensitivity handling for manufacturing.

L6563S Applications

The L6563S excels in high-performance power supplies, including:

• LED Drivers: Ensures stable, efficient power delivery for lighting systems.
• Server/Telecom PSUs: Meets 80 PLUS efficiency standards.
• Industrial SMPS: Provides robust PFC for motor drives and automation.
• Consumer Adapters: Compact design for laptops, TVs, and appliances.
  Its transition-mode operation makes it superior to fixed-frequency PFC controllers, offering better efficiency at light loads and reduced EMI noise.

Conclusion of L6563S

The L6563S stands out as a highly efficient, compact PFC controller for modern power electronics. Its low startup current, robust protection features, and compliance with environmental regulations make it ideal for energy-conscious designs. Whether in industrial, consumer, or telecom applications, it delivers reliable performance with minimal harmonic distortion, ensuring compliance with global power quality standards.
