Infineon Technologies AG PMIC - PMIC - AC DC Converters, Offline Switchers - ICE3AS02 ICE3AS02

The ICE3AS02 is an off-line switch mode power supply (SMPS) current mode controller designed for efficient power management. It features an integrated 500V startup cell and operates with a fixed switching frequency of 100 kHz. The controller incorporates an Active Burst Mode, which allows it to achieve standby power consumption of less than 100 mW at no load, making it suitable for energy-sensitive applications. This device includes multiple protection features such as Auto Restart Mode for overtemperature, VCC overvoltage, output open loop, overload, and VCC undervoltage conditions, enhancing system robustness and safety. The adjustable blanking window allows for improved reliability during high load jumps. The ICE3AS02 requires a minimal number of external components, contributing to a more compact design. It is compliant with RoHS and features soft switching to reduce electromagnetic interference (EMI). Engineers considering this product should note its suitability for applications requiring efficient power conversion with stringent standby power requirements and robust protection mechanisms.
