The ON Semiconductor NCP1601BP is a highly integrated Power Factor Correction (PFC) controller designed for use in a wide range of applications requiring efficient power conversion and power factor improvement. This advanced controller is suitable for AC-DC converters and off-line power supplies, making it an ideal choice for consumer electronics, industrial systems, and lighting solutions.

Key Features

• Critical Conduction Mode (CrM) Operation: The NCP1601BP operates in Critical Conduction Mode, which allows for zero current turn-off of the boost switch, reducing switching losses and improving overall efficiency.
• High Power Factor: Designed to achieve near-unity power factor, this controller significantly reduces harmonic distortion on the power line, ensuring compliance with international regulations such as EN61000-3-2.
• Low Startup Current: The device features a very low startup current, minimizing standby power consumption and making it well-suited for energy-sensitive applications.
• Integrated Protections: To ensure reliable operation, the NCP1601BP includes several protection features such as overvoltage protection (OVP), overcurrent protection (OCP), and undervoltage lockout (UVLO).
• Frequency Modulation for Reduced EMI: The controller offers frequency modulation to spread the electromagnetic interference (EMI) spectrum, facilitating easier compliance with EMI standards.
• Adjustable Output Overvoltage Protection: Users can set the desired level of overvoltage protection to match specific application requirements.
