The SD6802SETR is a highly integrated offline power switch IC manufactured by Silan Microelectronics. It's designed for cost-effective and efficient power supply solutions, primarily targeting applications requiring low standby power consumption and high reliability. This IC incorporates a current-mode PWM controller and a high-voltage power MOSFET, minimizing external components and simplifying the overall design.

Applications:

• Power adapters for mobile devices
• Standby power supplies for consumer electronics (TVs, DVD players, etc.)
• Open-frame power supplies
• LED lighting power supplies
• Battery chargers

Features:

• Built-in high-voltage power MOSFET
• Current-mode PWM control
• Low standby power consumption (<0.3W)
• Overcurrent protection (OCP)
• Overvoltage protection (OVP)
• Overtemperature protection (OTP)
• Short circuit protection (SCP)
• Frequency jittering for improved EMI performance
• Soft start to reduce stress on components during startup

Benefits:

• Reduced Bill of Materials (BOM): The integrated MOSFET and controller minimize the need for external components, lowering costs and simplifying the design process.
• High Efficiency: Current-mode PWM control and optimized design contribute to high efficiency, reducing energy consumption and heat dissipation.
• Improved Reliability: Comprehensive protection features (OCP, OVP, OTP, SCP) ensure robust and reliable operation, preventing damage to the power supply and connected devices.
• Low Standby Power: The SD6802SETR is designed for very low standby power consumption, meeting stringent energy efficiency requirements.
• Simplified Design: The high level of integration simplifies the design process, reducing development time and effort.

The SD6802SETR operates in quasi-resonant mode (QRM) to further enhance efficiency and reduce EMI. The built-in frequency jittering function further reduces EMI emissions, simplifying compliance with regulatory requirements. The soft-start feature minimizes stress on components during startup, enhancing reliability and extending the lifespan of the power supply.
