AC DC Converters, Offline Switches

NCP1338DR2G Description

The NCP1338DR2G from onsemi is a high-performance offline switch designed for flyback topology applications. This surface-mount IC integrates advanced control features to optimize power conversion in isolated AC/DC systems. Operating with a 130kHz switching frequency, it ensures efficient power delivery while minimizing electromagnetic interference (EMI). The device supports a 10V to 20V supply range and features a 12V startup voltage, making it suitable for a wide range of power supply designs. With RoHS3 compliance and REACH unaffected status, it meets stringent environmental and safety standards.

NCP1338DR2G Features

• Comprehensive Fault Protection: Includes current limiting, over-temperature, over-voltage, and short-circuit protection for robust system reliability.
• Isolated Output: Ensures safe operation in high-voltage applications.
• Wide Supply Range (10V–20V): Enhances flexibility in diverse power supply designs.
• 130kHz Switching Frequency: Balances efficiency and EMI performance.
• Compact 7SOIC Package: Ideal for space-constrained applications.
• Obsolete Status: While still functional, designers should consider newer alternatives for long-term availability.

NCP1338DR2G Applications

This IC is particularly suited for:

• AC/DC adapters and offline power supplies requiring isolated outputs.
• Auxiliary power modules in industrial and consumer electronics.
• LED drivers and battery chargers where fault protection is critical.
• Low-to-medium power flyback converters (e.g., set-top boxes, networking equipment).

Conclusion of NCP1338DR2G

The NCP1338DR2G offers a reliable, feature-rich solution for offline flyback converters, combining high efficiency with robust protection mechanisms. Its wide supply range and compact form factor make it versatile for various power applications. However, its obsolete status may prompt designers to explore newer alternatives from onsemi’s portfolio for future-proof designs. Ideal for legacy systems or applications where proven performance outweighs obsolescence concerns.
