The FAN6757MRMX from ON Semiconductor is an advanced PWM controller specially designed for high-performance offline Switch-Mode Power Supplies (SMPS). It integrates a variety of features that enhance the power supply efficiency and reliability, making it an ideal choice for applications such as LCD monitors, LED TVs, and other low-power electrical devices that require energy-saving capabilities.

Key Features:

• Green-Mode Function: The FAN6757MRMX incorporates an innovative green-mode function that helps in reducing standby power consumption. This feature ensures that the PWM controller enters green-mode operation at low load conditions, thereby minimizing power loss and saving energy.
• Internal High-Voltage Startup: This device includes an internal high-voltage startup circuit that allows the power supply to start up efficiently without the need for external components, simplifying the design and reducing overall costs.
• Frequency Modulation for EMI Reduction: To mitigate electromagnetic interference (EMI), the FAN6757MRMX has a built-in frequency modulation feature. This helps in spreading the EMI spectrum and allows the power supply to meet international EMI standards.
• Built-in Soft-Start: With an integrated soft-start function, the device ensures a gradual increase in the output voltage, which helps in preventing stress on the power supply components during startup.
• Protection Features: The FAN6757MRMX is equipped with multiple protection mechanisms, including over-voltage protection (OVP), over-current protection (OCP), and brown-in/out protection, enhancing the safety and durability of the power supply.
