ON Semiconductor FAN7602BM Green-Mode PWM Controller

The ON Semiconductor FAN7602BM is a highly integrated green-mode Pulse Width Modulation (PWM) controller designed for high-performance, compact, and energy-efficient power supply applications. It is an ideal solution for switch mode power supplies (SMPS) in a variety of consumer electronics, including DVD players, set-top boxes, and LCD monitors.

Key Features:

• Green Mode Operation: The FAN7602BM incorporates green-mode function that helps to reduce standby power consumption. When the load decreases, the IC automatically enters green-mode and provides excellent efficiency at light-load conditions by reducing the switching frequency to lower the switching loss.
• Burst Mode Operation: This feature allows the controller to operate in burst mode, which further reduces power consumption under light-load conditions, enhancing the efficiency of the power supply.
• High-Voltage Startup: The built-in high-voltage startup circuit ensures reliable startup of the power supply and reduces power loss.
• Frequency Modulation: To minimize Electromagnetic Interference (EMI), the FAN7602BM includes frequency modulation for reducing EMI emission of the power supply.
• Over-Voltage Protection: The device is equipped with over-voltage protection (OVP) to prevent the power supply from output voltage spikes that could damage connected devices.
• Under-Voltage Lockout: Under-voltage lockout (UVLO) ensures that the controller operates at the correct voltage levels, enhancing the safety and reliability of the power supply.
• Overload Protection: Overload protection (OLP) is implemented to prevent power supply damage in case of an unexpected increase in load.

Applications:

The versatility and energy-saving features of the FAN7602BM make it suitable for a wide range of applications, including:

• AC/DC adapters
• Open-frame SMPS
• Auxiliary power supplies for PCs and servers
• Telecom power supplies

With its comprehensive protection features and efficient performance, the FAN7602BM from ON Semiconductor is a robust choice for designers looking to enhance the performance and reliability of their power supply designs while meeting the stringent energy standards of today's electronic devices.
