It delivers up to 79 W in isolated flyback topologies, switching at 52 kHz with a fixed 50% duty cycle. Typical applications include auxiliary power supplies for industrial systems, AC-DC adapters, and bias supplies in motor drives or home appliances where a compact, single-chip solution is needed. ## Key ratings and what they mean for the BOM The 79 W output power rating defines the transformer core size and the secondary-side rectifier selection. The 650 V breakdown voltage on the internal CoolMOS switch gives headroom for universal AC input with reflected voltage and leakage spike margin. The 52 kHz switching frequency is a standard sweet spot: high enough to keep the transformer small, low enough that a simple RC snubber on the drain node handles ringing without excessive loss. The 10.5 V to 27 V Vcc range allows the IC to run off an auxiliary winding or a small bias supply without an external linear regulator. Fault protections include current limiting, overload, over-temperature, and over-voltage — all integrated, so no external comparators or watchdog circuits are needed. The 18 V startup voltage ensures the IC stays off until the bulk capacitor charges sufficiently, preventing hiccup on brownout conditions. ## Lifecycle and sourcing The ICE2QR0665ZXKLA1 carries an Active lifecycle status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For production BOMs, this part is suitable for new designs and ongoing volume builds.","metaTitle":"Infineon ICE2QR0665ZXKLA1 CoolSET Flyback, 79W, 650V","metaDescription":"Infineon ICE2QR0665ZXKLA1 CoolMOS/CoolSET offline flyback switcher, 79W, 650V breakdown, 52kHz, DIP-7, active.","metaKeywords":null},"attributes":{"series":"CoolMOS™, CoolSET™-Q1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"CoolMOS™, CoolSET™-Q1","Package":"Tube","Topology":"Flyback","Duty Cycle":"50%","Mounting Type":"Through Hole","Power (Watts)":"79 W","Package / Case":"8-DIP (0.300\\\", 7.62mm), 7 Leads","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting, Over Load, Over Temperature, Over Voltage","Output Isolation":"Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"18 V","Voltage - Breakdown":"650V","Frequency - Switching":"52kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"PG-DIP-7-4","Voltage - Supply (Vcc/Vdd)":"10.5V ~ 27V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.80000","currency":"USD"},{"qty":10,"price":"$2.51400","currency":"USD"},{"qty":25,"price":"$2.37200","currency":"USD"},{"qty":100,"price":"$2.02110","currency":"USD"},{"qty":250,"price":"$1.89772","currency":"USD"},{"qty":500,"price":"$1.66052","currency":"USD"},{"qty":1000,"price":"$1.44392","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/705060c847485396e96467f93944ba4d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ICE2QR0665ZXKLA1 lead-free?","answer":"Yes, it is ROHS3 compliant, meaning it meets the lead-free and restricted-substance requirements of the EU RoHS directive."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/ICE2QR0665ZXKLA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/ICE2QR0665ZXKLA1 when reusing this data.
