It supports buck, buck-boost, and flyback topologies with a fixed 60 kHz switching frequency. The 800 V breakdown gives enough headroom for universal AC input (85–265 VAC) rectified to ~375 VDC, with margin for line transients. The 12 W output ceiling is practical for auxiliary supplies in appliances, metering, and industrial control boards. ## Start-up voltage, supply range, and protection Fault protection includes over-load and over-voltage shutdown. The soft-start feature reduces inrush stress on the output capacitor during power-up. ## Active lifecycle, 10-SSOP package, sourcing posture ROHS3 compliant. The 10-SSOP package (3.90 mm width) is a surface-mount footprint suited for automated assembly. Sourced per RFQ — confirm current lead time and pricing with your order quantity.","metaTitle":"VIPER114LSTR STMicroelectronics Offline Switcher IC 800V","metaDescription":"VIPER114LSTR STMicroelectronics offline switching regulator IC. 800 V breakdown, 12 W output, buck/buck-boost/flyback topology.","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)":"12 W","Package / Case":"10-SOP (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"Soft Start","Fault Protection":"Over Load, Over Voltage","Output Isolation":"Non-Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"16 V","Base Product Number":"VIPER114","Voltage - Breakdown":"800V","Frequency - Switching":"60kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"10-SSOP","Voltage - Supply (Vcc/Vdd)":"4.5V ~ 30V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3500","priceTiers":[{"qty":1,"price":"$1.35000","currency":"USD"},{"qty":10,"price":"$1.21000","currency":"USD"},{"qty":25,"price":"$1.14840","currency":"USD"},{"qty":100,"price":"$0.94340","currency":"USD"},{"qty":250,"price":"$0.88184","currency":"USD"},{"qty":500,"price":"$0.77930","currency":"USD"},{"qty":1000,"price":"$0.61524","currency":"USD"},{"qty":2500,"price":"$0.57422","currency":"USD"},{"qty":5000,"price":"$0.54551","currency":"USD"},{"qty":12500,"price":"$0.52501","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/581b715f318faca79ea625c67bb64fdf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER114LSTR/alternatives.json"},"ai":{"faq":[{"question":"How can I order VIPER114LSTR or check availability?","answer":"VIPER114LSTR is an active STMicroelectronics part.
