ICE2A180Z

ICE2A180Z Description

The ICE2A180Z from Infineon Technologies is an offline switch flyback controller designed for AC/DC converter applications. Part of the CoolSET®F2 series, this obsolete through-hole-mounted IC integrates an 800V breakdown voltage MOSFET and operates with a 100kHz switching frequency, delivering up to 29W of power. It features isolated output and supports an input voltage range of 8.5V to 21V, with a 13.5V startup voltage for reliable initialization. The device is housed in a 7DIP package and complies with REACH Unaffected and EAR99 regulations, making it suitable for various power supply designs.

ICE2A180Z Features

• Integrated 800V MOSFET for high-voltage handling in offline applications.
• Soft Start & Fault Protection including current limiting, open-loop detection, overload, over-temperature, and over-voltage protection for enhanced system reliability.
• 72% duty cycle and 100kHz switching frequency for efficient power conversion.
• Wide Vcc range (8.5V–21V) with low startup voltage (13.5V), ensuring stable operation under varying conditions.
• Isolated output topology (Flyback) for safety and noise immunity in power supply designs.
• 1 (Unlimited) MSL rating for robust handling in manufacturing environments.

ICE2A180Z Applications

The ICE2A180Z is ideal for:

• Low-to-medium power offline SMPS (e.g., adapters, chargers).
• Auxiliary power supplies in industrial and consumer electronics.
• LED drivers requiring high-voltage isolation and protection features.
• Household appliances where reliability and fault protection are critical.

Conclusion of ICE2A180Z

The ICE2A180Z offers a compact, high-performance solution for offline flyback converters, combining high-voltage resilience, integrated protection, and efficient switching. While now obsolete, its robust design and Infineon’s CoolSET®F2 technology make it a dependable choice for legacy or niche applications requiring isolated power conversion with minimal external components. Engineers may consider alternative CoolSET® series models for newer designs.
