The SG6860TZ from ON Semiconductor is a highly efficient, low-power green-mode PWM (Pulse Width Modulation) controller that is designed to meet the rigorous demands of modern power supply applications. This innovative component is engineered to provide a compact and energy-efficient solution for AC-DC power conversion in a wide range of electronic devices.

The SG6860TZ is particularly suitable for use in switch-mode power supplies (SMPS) where energy conservation is of paramount importance. It is often found in applications such as battery chargers, adapters, standby power supplies, and other auxiliary power systems. Its green-mode operation ensures that the power supply maintains ultra-low power consumption at no-load or light-load conditions, significantly reducing energy waste and contributing to overall system efficiency.

Key Features

• High Efficiency: The controller's green-mode function ensures optimal efficiency by automatically reducing switching frequency under light-load conditions, which minimizes standby power consumption.
• Integrated Protections: SG6860TZ comes with built-in over-voltage protection, over-current protection, and under-voltage lockout, enhancing the safety and reliability of the power supply.
• Frequency Modulation: To mitigate EMI (Electromagnetic Interference), the device employs frequency modulation, which helps in meeting regulatory EMI requirements.
• Low Startup Current: The controller is designed with a low startup current, which reduces power loss during the initial power-up sequence.
• Direct Drive Capability: The SG6860TZ can directly drive a high-power MOSFET, simplifying the circuit design and reducing component count.

Applications

• AC/DC Adapters
• Open Frame Switching Power Supplies
• Standby and Auxiliary Power Supplies
• Power Supplies for Set-Top Boxes, Networking Devices, and Peripherals

ON Semiconductor's SG6860TZ is a testament to the company's dedication to creating products that not only enhance performance but also support environmental sustainability through reduced power usage. The integration of advanced features and protections ensures that the SG6860TZ is a reliable and versatile choice for designers looking to optimize their power supply solutions.
