It's the kind of part you find in AC-DC power supplies for consumer electronics, home appliances, and industrial auxiliary supplies where isolated output and moderate power (typically under 100W) are needed. The internal switch simplifies the BOM — no external MOSFET to source, no gate-drive loop to lay out. The 8.5V to 21V Vcc range gives flexibility on the bias winding design, and the -25°C to 130°C junction temperature covers most indoor and ventilated-enclosure environments. ## Fault protections — what shuts it down and what doesn't This controller integrates current limiting, open-circuit detection, over-load, over-temperature, and over-voltage protection. ## Active production — no LTB scramble The ICE3B1565 is listed as Active in production and ROHS3 compliant.","metaTitle":"Infineon ICE3B1565 Offline Flyback Controller, 650V, 67kHz","metaDescription":"Infineon ICE3B1565 offline flyback switch with 650V breakdown, 67kHz switching, active production, ROHS3.

These cover the common failure modes in a flyback converter without external supervisory components."},{"question":"What is the switching frequency of ICE3B1565?","answer":"The ICE3B1565 switches at 67kHz fixed frequency. That's a typical mid-range value for cost-optimized flyback converters — fast enough to keep transformer size small, slow enough to avoid excessive switching losses and EMI headaches."},{"question":"Is ICE3B1565 suitable for isolated flyback designs?","answer":"Yes, the ICE3B1565 is designed for isolated flyback topologies, as noted in its spec. The internal 650V MOSFET and comprehensive fault protection make it a good fit for off-line AC-DC converters requiring galvanic isolation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/ICE3B1565","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/ICE3B1565 when reusing this data.
