ON Semiconductor NCP1615CDR2G Power Factor Controller

The ON Semiconductor NCP1615CDR2G is a highly integrated and efficient power factor controller designed for use in continuous conduction mode (CCM) power factor correction (PFC) applications. This advanced controller is an ideal solution for systems such as switch-mode power supplies, LED drivers, and other power conversion equipment that require improved power factor and reduced total harmonic distortion.

Key Features

• Continuous Conduction Mode (CCM) Operation: The NCP1615CDR2G operates in CCM, which ensures stable and efficient performance for high power applications.
• High Power Factor: This controller is engineered to achieve near-unity power factor, which minimizes reactive power on the electrical grid and enhances the efficiency of the power supply.
• Low Total Harmonic Distortion (THD): It significantly reduces harmonic distortion, leading to cleaner power delivery and compliance with global power quality standards.
• Adjustable Output Voltage: The NCP1615CDR2G allows for precise control over the output voltage, providing flexibility to accommodate various application requirements.
• Brown-Out Protection: The built-in brown-out protection ensures that the controller operates reliably under conditions of undervoltage, safeguarding the power supply and the end equipment.
• Overvoltage Protection (OVP): It offers OVP to prevent damage to the power supply and connected devices in the event of voltage spikes.
• Soft-Start Capability: The soft-start feature minimizes inrush current during startup, contributing to the longevity of the system and reducing stress on components.
• Frequency Modulation for Reduced EMI: The controller modulates the switching frequency to spread the electromagnetic interference (EMI) spectrum, facilitating easier compliance with EMI regulations.
