It's part of the FSQ-series, an integrated Pulse-Width Modulation controller and SenseFET specifically designed for valley switching operation with minimal external components, which generally shows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The PWM controller includes an integrated fixed-frequency oscillator, under-voltage lockout, and Leading-Edge Blanking (LEB). Combining the controller and power switch into one die reduces total component count, board space, and BOM cost compared to a discrete MOSFET + PWM controller solution — a common approach in compact chargers, adapters, and small SMPS boards.\u003cspan class=\"inline-flex\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eKey Specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eType: Integrated PWM Controller + Power MOSFET (Fairchild Power Switch)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eManufacturer: onsemi (formerly Fairchild Semiconductor)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePackage Marking: Q0265R\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePackage: 8-Pin DIP (PDIP-8)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDrain-Source Voltage: 650V\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRated Current: 2A\u003cspan class=\"inline-flex\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSwitching Topology: Quasi-resonant \/ valley switching (Green Mode)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBuilt-in protections: Under-voltage lockout, Leading-Edge Blanking, self-protection circuitry\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRoHS compliant (typical for this series)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCommon Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAC-DC switch-mode power adapters\/chargers\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOffline flyback converters (typically for supplies around 16W) \u003cspan class=\"inline-flex\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLCD\/LED TV and monitor power boards\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAuxiliary\/standby power supplies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1 x onsemi FSQ0265RN Power Switch IC (8-Pin DIP)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"digilog.pk","offers":[{"title":"Default Title","offer_id":51670213460246,"sku":null,"price":0.0,"currency_code":"PKR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/0764\/1366\/files\/FSQ0265RN650V2AGreenModeFairchildPowerSwitch8PinIC.jpg?v=1786176354","url":"https:\/\/digilog.pk\/products\/fsq0265rn-650v2a-green-mode-fairchild-power-switch-8-pin-ic","provider":"digilog.pk","version":"1.0","type":"link"}
