NCP1615D2DR2G

NCP1615D2DR2G Description

The NCP1615D2DR2G from onsemi is a high-performance Power Factor Correction (PFC) controller IC designed for current-controlled frequency foldback (CCFF) and critical conduction mode (CRM) operation. This surface-mount device operates at a switching frequency of 26kHz with a wide supply voltage range of 9.5V to 28V, making it suitable for robust power management applications. Packaged in a 16-pin SOIC and delivered in Tape & Reel (TR), it complies with ROHS3 and REACH environmental standards. Although marked as obsolete, it remains a reliable choice for legacy designs requiring efficient PFC solutions.

NCP1615D2DR2G Features

• Dual-Mode Operation: Combines CCFF for improved light-load efficiency and CRM for reduced switching losses.
• Low Startup Current: 12 mA ensures quick and reliable power-up.
• Wide Voltage Range: Supports 9.5V–28V input, ideal for industrial and automotive applications.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity ensures durability in harsh environments.
• Regulatory Compliance: EAR99 and ROHS3 certified for global deployment.

NCP1615D2DR2G Applications

• AC-DC Power Supplies: Enhances power factor correction in SMPS and LED drivers.
• Industrial Systems: Suitable for motor controls and PLC power modules due to its robust voltage range.
• Consumer Electronics: Optimizes efficiency in TV power boards and adapter designs.
• Legacy Upgrades: Ideal for retrofitting older PFC circuits requiring high efficiency at partial loads.
