NCP1216AP100G

NCP1216AP100G Description

The NCP1216AP100G from onsemi is an offline switching controller designed for flyback topology applications in AC/DC power conversion. Housed in a 7-pin DIP (Through Hole) package, this obsolete but robust IC operates within a 10V to 16V supply range and delivers a fixed switching frequency of 100kHz. It supports isolated outputs and is compliant with ROHS3 and REACH environmental standards. With a duty cycle of 46.5%, it ensures stable performance in demanding power supply designs.

NCP1216AP100G Features

• High Reliability: Operates across a wide junction temperature range (0°C to 150°C).
• Comprehensive Protection: Integrates overload, over-temperature, and short-circuit protection for enhanced system safety.
• Fixed-Frequency Operation: 100kHz switching ensures predictable noise characteristics and simplifies EMI filtering.
• Isolated Output: Suitable for designs requiring galvanic isolation.
• Low Moisture Sensitivity: MSL 1 (Unlimited) rating ensures ease of handling and storage.
• RoHS3 Compliant: Meets stringent environmental regulations.

NCP1216AP100G Applications

This IC is ideal for:

• Low-to-medium power offline SMPS (Switched-Mode Power Supplies).
• Auxiliary power supplies in industrial and consumer electronics.
• Battery chargers and adapter circuits requiring stable isolated outputs.
• LED drivers and household appliances where fault protection is critical.

Conclusion of NCP1216AP100G

The NCP1216AP100G offers a balanced combination of performance, protection, and reliability, making it a strong choice for offline flyback converters.
