Rated for 100 W of output power, it supports switching frequencies up to 200 kHz, which lets the designer use a smaller transformer core than a 100 kHz design would allow. ## Built-in control and protection reduce BOM count The controller includes an internal start-up regulator (11 V start-up threshold), soft-start, frequency control, and an enable pin — features that eliminate several external bias and sequencing components. Fault protection covers current limiting and over-temperature shutdown, so the supply rail is self-protecting against output shorts and thermal runaway without a discrete sense resistor or thermistor.","metaTitle":"STMicroelectronics VIPER100A Flyback Converter, 700V, 100W","metaDescription":"VIPER100A from STMicroelectronics: monolithic flyback switcher, 700V breakdown, 100W, up to 200 kHz.","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":"Surface Mount","Power (Watts)":"100 W","Package / Case":"Pentawatt-5 HV (Bent and Staggered Leads)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"EN, Frequency Control, Soft Start","Fault Protection":"Current Limiting, Over Temperature","Output Isolation":"Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"11 V","Base Product Number":"VIPER100","Voltage - Breakdown":"700V","Frequency - Switching":"Up to 200kHz","Operating Temperature":"-","Supplier Device Package":"5-PENTAWATT","Voltage - Supply (Vcc/Vdd)":"8V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99073a5c1c042db90590e56b869b4631.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER100A/alternatives.json"},"ai":{"faq":[{"question":"What is the operating frequency of VIPER100A?","answer":"The VIPER100A supports switching frequencies up to 200 kHz, allowing transformer size reduction compared to lower-frequency designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/VIPER100A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/VIPER100A when reusing this data.
