It delivers up to 10 W in an isolated flyback topology, switching at 136 kHz to keep the transformer compact. ## Fault protection and supply range Built-in fault protection covers current limiting, over-temperature, and over-voltage — reducing the external protection components needed around the controller. The Vcc supply range of 8.5 V to 23.5 V with a 14 V start-up threshold gives the designer a clean window for bias winding design.","metaTitle":"STMicroelectronics VIPER15LD VIPer™ plus Flyback, 10 W","metaDescription":"VIPER15LD is an obsolete STMicroelectronics VIPer™ plus flyback switcher with integrated 800 V MOSFET, rated 10 W.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"VIPer™ plus","Package":"Tube","Topology":"Flyback","Duty Cycle":"-","Mounting Type":"Surface Mount","Power (Watts)":"10 W","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Fault Protection":"Current Limiting, Over Temperature, Over Voltage","Output Isolation":"Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"14 V","Base Product Number":"VIPER15","Voltage - Breakdown":"800V","Frequency - Switching":"136kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"16-SO","Voltage - Supply (Vcc/Vdd)":"8.5V ~ 23.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dc2f05ea71906ee9d7493b4157cfdc4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER15LD/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for VIPER15LD?","answer":"No official replacement part number is recorded for the VIPER15LD.
