It switches at 100 kHz and operates from a Vcc supply rail of 8.5 V to 21 V, with a startup threshold of 13.5 V. The 72% maximum duty cycle sets the on-time ceiling for the primary switch, which matters when sizing the transformer turns ratio and bulk capacitor for hold-up time. ## Protection and control feature set Built-in fault protection covers current limiting, open-loop detection, overload, over-temperature, and over-voltage conditions — the controller shuts down or folds back without external supervisory circuitry. A soft-start function ramps the duty cycle on power-up, reducing inrush stress on the output capacitor and the primary MOSFET. Output isolation is supported — the controller drives a primary-side switch while the feedback loop crosses the isolation barrier via an optocoupler or a transformer winding. The narrow-body SOIC footprint is standard for low-pin-count power controllers and mates with common 1.27 mm pitch land patterns. Supplied in Bulk packaging — no tape-and-reel quantity, so plan for tube or tray handling at the pick-and-place feeder. Confirm the BOM position against the PG-DSO-8 footprint before committing the layout.","metaTitle":"Infineon ICE2AS01GHUMA1 Offline Flyback Controller, 100kHz","metaDescription":"Infineon ICE2AS01GHUMA1 offline flyback PWM controller. 100kHz switching, 8.5-21V supply, -40 to 150°C.
