TOP232GN

TOP232GN Description

The TOP232GN from Power Integrations is a high-performance offline switching IC designed for flyback topology applications, offering isolated output and surface-mount compatibility (8SMD package). With a 700V breakdown voltage and an integrated 66kHz–132kHz frequency control, it delivers up to 15W of power with 78% duty cycle efficiency. This device is RoHS compliant, REACH unaffected, and rated for MSL 4 (72 hours), making it suitable for demanding industrial environments. Its built-in fault protection (current limiting, over-temperature, and over-voltage) ensures robust operation in variable load conditions.
