It targets offline AC-DC converters in the 50 W range — think appliance power supplies, battery chargers, auxiliary housekeeping rails in industrial gear, and white-goods control boards. The built-in 800 V avalanche-rated MOSFET handles the primary-side switching directly, so the bill of materials stays tight: no external power switch, no separate gate-drive components. Switching at 100 kHz with a 72% maximum duty cycle, the ICE2A280 is tuned for a transformer size that balances cost and efficiency in a 50 W design. The controller runs from an 8.5 V to 21 V Vcc rail and includes a full set of fault protections — current limiting, open-loop detection, overload, over-temperature, and over-voltage — so a single-ended flyback built around this part can meet IEC/UL safety requirements without a separate supervisor IC. ## Package and mounting The integrated MOSFET has an 800 V drain-source breakdown voltage. The 50 W output power ceiling is a practical limit for continuous operation in an enclosed PSU. The 100 kHz switching frequency is a sweet spot for a 50 W flyback: high enough to keep the transformer core small, low enough that a standard ultrafast recovery diode on the secondary side handles the reverse-recovery losses without a SiC upgrade. The 72% duty cycle cap means the controller leaves enough off-time for the transformer to reset. ## Through-hole DIP-7 — repair-bench friendly The PG-DIP-7-1 package is a through-hole part. That is good news if you are on the rework or repair side: you can pull and replace it with a soldering iron and a desoldering pump. ## Fault protections and soft start — what is covered The ICE2A280 includes current limiting, open-loop detection, overload, over-temperature, and over-voltage protection. The over-temperature protection uses the junction temperature sense — if the die hits the thermal shutdown threshold, the PWM stops and restarts after a cool-down hysteresis. Soft start ramps the duty cycle gradually at power-up, which prevents transformer saturation and output overshoot on the first few cycles.","metaTitle":"Infineon ICE2A280 CoolSET F2 Flyback PWM, 100 kHz, 800 V","metaDescription":"ICE2A280 is an 800 V CoolSET F2 flyback PWM controller with integrated MOSFET, 100 kHz switching, 50 W output, through-hole DIP-7.
