It delivers up to 20 W in flyback, buck, or buck-boost topologies, making it a fit for auxiliary supplies, appliance power boards, and industrial control power stages. ## 1050 V breakdown and 150 °C junction — margin for universal mains The 1050 V breakdown voltage gives headroom above the typical 800 V peak on a 265 VAC line with reflected voltage — you can skip external snubber components in many designs. Sourced to order against your BOM line — confirm availability and current pricing through an RFQ. ## Protection set and supply range Built-in fault protection covers current limiting, overload, and short-circuit conditions. The controller includes an enable pin and a soft-start feature for controlled ramp-up. The VCC supply range is 11.5 V to 23.5 V with a 13 V start-up threshold, compatible with standard bias windings or auxiliary supplies.","metaTitle":"VIPER265KDTR ST VIPER™ Offline Switcher, 20 W, 1050 V","metaDescription":"VIPER265KDTR from STMicroelectronics — offline switching regulator, 20 W output, 1050 V breakdown, 60 kHz fixed frequency, 16-SOIC package.","metaKeywords":null},"attributes":{"series":"VIPER™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"VIPER™","Package":"Tape & Reel (TR) Cut Tape (CT)","Topology":"Buck, Buck-Boost, Flyback","Duty Cycle":"80%","Mounting Type":"Surface Mount","Power (Watts)":"20 W","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"EN, Soft Start","Fault Protection":"Current Limiting, Over Load, Short Circuit","Output Isolation":"Either","Internal Switch(s)":"Yes","Voltage - Start Up":"13 V","Base Product Number":"VIPER265","Voltage - Breakdown":"1050V","Frequency - Switching":"60kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"16-SO","Voltage - Supply (Vcc/Vdd)":"11.5V ~ 23.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1400","priceTiers":[{"qty":1,"price":"$2.14000","currency":"USD"},{"qty":10,"price":"$1.92400","currency":"USD"},{"qty":25,"price":"$1.81480","currency":"USD"},{"qty":100,"price":"$1.54610","currency":"USD"},{"qty":250,"price":"$1.45176","currency":"USD"},{"qty":500,"price":"$1.27030","currency":"USD"},{"qty":1000,"price":"$1.05254","currency":"USD"},{"qty":2500,"price":"$0.97995","currency":"USD"},{"qty":5000,"price":"$0.94365","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f5cf278018dc3b2c94270e784af7c382.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER265KDTR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum output power of the VIPER265KDTR?","answer":"The device is rated for 20 W output in flyback, buck, or buck-boost topologies.
