NCP1216AP65G

NCP1216AP65G Description

The NCP1216AP65G from onsemi is an obsolete offline switch-mode power supply (SMPS) controller designed for flyback topology applications. Housed in a 7-pin DIP through-hole package, this IC operates within a 10V to 16V supply range and delivers a fixed 65kHz switching frequency with a 46.5% duty cycle. It supports isolated output configurations, making it suitable for AC/DC power conversion in various offline power supplies. The device is RoHS3 compliant and adheres to REACH Unaffected standards, ensuring environmental and regulatory compliance.

NCP1216AP65G Features

• Robust Fault Protection: Integrates overload, over-temperature, and short-circuit protection for enhanced system reliability.
• Wide Operating Temperature: Functions reliably from 0°C to 150°C (TJ), making it suitable for demanding environments.
• Fixed 65kHz Frequency: Ensures stable performance with minimal external components, reducing design complexity.
• Isolated Output: Supports transformer-coupled designs for safety-critical applications.
• Low External Component Count: Optimized for cost-effective designs without compromising performance.

NCP1216AP65G Applications

• AC/DC Adapters: Ideal for low-to-medium power offline converters in consumer electronics.
• Auxiliary Power Supplies: Used in industrial systems, telecom equipment, and appliances requiring isolated power rails.
• LED Drivers: Suitable for driving LED arrays in lighting applications due to its stable switching characteristics.
• Household Electronics: Powers devices like set-top boxes, routers, and small appliances.

Conclusion of NCP1216AP65G

The NCP1216AP65G is a versatile, albeit obsolete, flyback controller offering high reliability, integrated protection, and ease of design. While newer alternatives may exist, its 65kHz operation, isolation capability, and robust fault handling make it a viable choice for legacy or cost-sensitive offline power supply designs. Engineers should evaluate replacement options from onsemi's current portfolio for long-term availability.
