ON Semiconductor NCP1618BDR2G Power Factor Correction Controller

The NCP1618BDR2G is a high-performance, critical conduction mode (CrM) power factor correction (PFC) controller designed by ON Semiconductor. This advanced integrated circuit (IC) is engineered to deliver efficient power regulation for a wide range of applications, including but not limited to power supplies for televisions, desktop computers, servers, and industrial systems. With its state-of-the-art features, the NCP1618BDR2G is an ideal solution for systems that require compliance with regulatory standards for power factor and harmonic content.

Key Features

• High-Efficiency CrM Operation: The NCP1618BDR2G operates in critical conduction mode, which minimizes switching losses and improves overall efficiency, particularly beneficial in light load conditions.
• Adjustable Output Overvoltage Protection: This feature safeguards the power supply and the load by promptly shutting down the PFC stage if an overvoltage condition is detected.
• Low Startup Current: The device boasts a low startup current, which reduces stress on the system during power-up, enhancing the reliability and lifespan of the power supply.
• Brownout Protection: In the event of a brownout, the NCP1618BDR2G automatically reduces the power delivered to prevent system shutdown, thereby maintaining performance during dips in input voltage.
• Frequency Limitation: The IC includes a frequency limitation feature to prevent operation at undesirably high frequencies, thus ensuring reliable performance and compliance with EMI standards.

Applications

The versatility of the NCP1618BDR2G makes it suitable for a variety of applications that demand high power factor and low THD (Total Harmonic Distortion). It is commonly used in:

• AC-DC Adapters
• Power Supplies for Flat Panel Televisions
• Desktop and Server Power Supplies
• Industrial Power Systems
