The 800 V breakdown voltage gives real margin for universal AC input (85–265 VAC) designs: the reflected voltage plus leakage spike stays well within the MOSFET's safe operating area, even with a loosely coupled transformer. The 52 kHz switching frequency is a practical middle ground — the transformer core is small enough for a compact footprint, yet the switching losses stay low enough that a through-hole DIP package can dissipate the heat without a heatsink in many 30–40 W designs. Fault protection covers the common failure modes: current limiting, overload, over-temperature, and over-voltage are all on-chip, so the controller latches off or auto-restarts without external supervision. The output is isolated, meaning the feedback loop crosses the isolation barrier via an optocoupler — standard for mains-isolated supplies. ## Through-hole PG-DIP-7-4 — why it matters for your assembly line The PG-DIP-7-4 package is a 7-lead through-hole DIP with a 0.300-inch body width. It is a direct fit for wave-solder or hand-assembly lines, and it stands up to vibration better than a surface-mount part in the same power range — something to consider if the supply lives on a motor drive or in an industrial cabinet. The 7-lead variant includes the drain tab as a dedicated pin for thermal conduction to the PCB copper. The supply voltage range of 10.5 V to 27 V on Vcc gives flexibility for bias winding design: you can set the auxiliary winding for a nominal 15 V or 18 V and still have headroom during start-up transients. The start-up voltage threshold is 18 V, after which the internal start-up current source turns off, reducing power dissipation in the IC. No special handling or exemption tracking is needed.","metaTitle":"ICE2QR2280ZXKLA1 CoolSET™-Q1 Flyback Switcher, 800V, 54W","metaDescription":"Infineon ICE2QR2280ZXKLA1 offline flyback switcher, 800V breakdown, 54W, 52kHz, PG-DIP-7-4 through-hole.","metaKeywords":null},"attributes":{"series":"CoolMOS™, CoolSET™-Q1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"CoolMOS™, CoolSET™-Q1","Package":"Tube","Topology":"Flyback","Duty Cycle":"50%","Mounting Type":"Through Hole","Power (Watts)":"54 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":"800V","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":"$2.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.97000","currency":"USD"},{"qty":10,"price":"$2.66900","currency":"USD"},{"qty":25,"price":"$2.52280","currency":"USD"},{"qty":100,"price":"$2.18650","currency":"USD"},{"qty":250,"price":"$2.07440","currency":"USD"},{"qty":500,"price":"$1.86136","currency":"USD"},{"qty":1000,"price":"$1.56982","currency":"USD"},{"qty":2500,"price":"$1.49133","currency":"USD"},{"qty":5000,"price":"$1.43527","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/68df76b04ec3023e9c7802351461d348.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ICE2QR2280ZXKLA1 obsolete?","answer":"Infineon has not issued a discontinuation notice for this part."},{"question":"What is the maximum power of ICE2QR2280ZXKLA1?","answer":"The ICE2QR2280ZXKLA1 is rated for 54 W in a flyback topology.
