The SSC2S110-TL is a quasi-resonant type flyback PWM controller manufactured by Sanken Electric. The "-TL" suffix typically denotes a specific packaging or taping option for automated assembly. Functionally, it shares the same core features and benefits as the SSC2S110, focusing on efficiency, low noise, and simplified design for power supply systems.

Applications:

• AC/DC adapters
• Auxiliary power supplies in white goods
• Consumer electronics power supplies (e.g., TVs, Blu-ray players)
• Industrial power supplies
• Power supplies for office automation equipment (e.g., printers, copiers)

Features:

• Quasi-Resonant Operation: Operates in quasi-resonant mode, reducing switching losses and EMI noise.
• Valley Detection: Employs valley detection to minimize switching losses and improve efficiency.
• Low Standby Power: Designed for low standby power consumption, meeting energy efficiency standards.
• Built-in Soft Start Function: Includes a soft start function to reduce stress on components during startup.
• Protection Features: Incorporates comprehensive protection features such as Over Current Protection (OCP), Over Voltage Protection (OVP), and Over Load Protection (OLP).
• Brown-In and Brown-Out Protection: Protects the power supply against voltage fluctuations on the input side.
• Built-in Leading Edge Blanking (LEB): Minimizes the influence of switching noise.
• Automatic Burst Mode Operation: Supports burst mode operation under light load conditions for improved efficiency.

Benefits:

• High Efficiency: Quasi-resonant operation and valley detection contribute to high efficiency across a wide load range.
• Reduced EMI Noise: Quasi-resonant operation minimizes EMI noise, simplifying system design and reducing the need for external filtering.
• Low Standby Power Consumption: Meets stringent energy efficiency requirements, reducing energy waste.
• Enhanced System Reliability: Comprehensive protection features protect the power supply and connected devices from damage.
• Simplified Design: Integrated features such as soft start and LEB simplify the design process and reduce component count.
• Stable Operation: Brown-in and Brown-out protection ensure stable operation even with input voltage fluctuations.
