It operates at a fixed 100 kHz switching frequency with a 75% maximum duty cycle, and includes a full protection suite covering current limiting, open loop, overload, over-temperature, and over-voltage faults. The part is packaged in an 8-SOIC (PG-DSO-8) footprint for surface-mount assembly, and is rated for junction temperatures from -40°C to 150°C. Typical applications include auxiliary power supplies, AC-DC adapters, and industrial bias rails where a compact, protected flyback stage is needed. ## 60 W power rating and 100 kHz switching — what they mean for the BOM The 60 W output capability sets the transformer and bulk capacitor sizing — expect a core in the EFD20/25 range and a 400 V bulk cap around 33–47 µF for universal AC input. The 100 kHz switching frequency is a sweet spot for transformer size versus switching losses; it keeps the flyback transformer compact while staying below the point where snubber losses dominate. The 75% duty cycle ceiling gives headroom for low-line operation (85 VAC) without hitting the max on-time limit. The internal power switch simplifies the layout — no external MOSFET selection or gate-drive loop to tune. The 10 V to 25.5 V Vcc range covers the output of a standard auxiliary winding, and the 16 V start-up threshold ensures clean power-on sequencing. ## Protection features and control interface The ICE5ASAGXUMA1 integrates EN (enable), Soft Start, and Sync control pins, allowing external on/off control, programmable soft-start ramp, and synchronization to an external clock if needed. The fault protection covers current limiting, open-loop detection, overload, over-temperature, and over-voltage — reducing the need for external supervisory circuitry in the BOM. ## Lifecycle and sourcing posture The ICE5ASAGXUMA1 carries an Active lifecycle status per the Infineon product record and is ROHS3 compliant. There is no LTB notice or successor part on file. ## Package and rework considerations The 8-SOIC (0.154\" body width, 3.90 mm) package is a standard surface-mount footprint with a 1.27 mm pitch. No exposed thermal pad — junction temperature is managed through the leadframe and PCB copper. For rework, standard SOIC hot-air profiles at 260°C peak (10 s max) are safe;.","metaTitle":"Infineon ICE5ASAGXUMA1 Offline Flyback Controller, 60 W","metaDescription":"Infineon ICE5ASAGXUMA1 offline flyback switch, 60 W power, 100 kHz switching, 8-SOIC package.

This is the maximum continuous power; derating is recommended for high ambient temperatures or tight enclosures."},{"question":"How does ICE5ASAGXUMA1 compare to the older ICE2QR2280G1XUMA1?","answer":"The ICE2QR2280G1XUMA1 is a quasi-resonant CoolSET-Q1 flyback controller rated for 53 W at 52 kHz with isolated output, while the ICE5ASAGXUMA1 is a fixed-frequency 100 kHz PWM controller rated for 60 W in a non-isolated topology. The ICE5ASAGXUMA1 switches at nearly double the frequency and offers a higher duty cycle (75% vs 50%), which affects transformer design and EMI filtering.

As long as the board footprint matches the 8-SOIC land pattern, it is a direct replacement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/ICE5ASAGXUMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/ICE5ASAGXUMA1 when reusing this data.
