It delivers up to 20 W in an isolated topology — enough for auxiliary supplies, appliance power boards, and industrial control bias rails. The internal start-up circuit (11 V start-up threshold) and fault protection (current limiting, over-temperature) reduce external component count. ## 700 V breakdown — headroom for universal input The 700 V breakdown rating gives the VIPER20ADIP-E comfortable margin on rectified 230 VAC (≈325 VDC) and even on 277 VAC lines common in industrial lighting. The switching frequency runs up to 200 kHz, which lets the designer shrink the flyback transformer core compared to a 100 kHz design — useful when board space is tight. Supply range is 8 V to 15 V on Vcc, so a simple auxiliary winding can bias it. ## Obsolete — no official successor listed The VIPER20ADIP-E is marked obsolete by STMicroelectronics. No direct pin-compatible replacement or successor order code is recorded in the lifecycle data.","metaTitle":"ST VIPER20ADIP-E flyback switcher, 20 W, 700 V, obsolete","metaDescription":"STMicroelectronics VIPER20ADIP-E offline flyback switcher: 20 W output, 700 V breakdown, up to 200 kHz, isolated topology.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"VIPER™","Package":"Tube","Topology":"Flyback","Duty Cycle":"-","Mounting Type":"Through Hole","Power (Watts)":"20 W","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Fault Protection":"Current Limiting, Over Temperature","Output Isolation":"Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"11 V","Base Product Number":"VIPER20","Voltage - Breakdown":"700V","Frequency - Switching":"Up to 200kHz","Operating Temperature":"-","Supplier Device Package":"8-DIP","Voltage - Supply (Vcc/Vdd)":"8V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dc35083aac10b9fba001b35a7ca87e04.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER20ADIP-E/alternatives.json"},"ai":{"faq":[{"question":"What is the closest replacement or equivalent for the VIPER20ADIP-E?","answer":"No pin-compatible replacement or official cross-reference is listed in the available lifecycle data.
