There is no frequency-foldback or spread-spectrum option, so the EMI filter must handle the fundamental and its harmonics at full load. The 8 V to 38 V supply range on Vcc lets the IC run directly from an auxiliary winding once the converter starts up at 14.5 V. ## Built-in fault protections — current limit, OTP, OVP On-chip fault protection includes current limiting, over-temperature shutdown, and over-voltage protection.","metaTitle":"STMicroelectronics VIPER22ADIP Flyback Converter, 12 W","metaDescription":"Obsolete ST VIPER22ADIP flyback switching regulator, 12 W output, 730 V breakdown, 60 kHz fixed frequency, 8-DIP through-hole.","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)":"12 W","Package / Case":"8-DIP (0.300\\\", 7.62mm)","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":"14.5 V","Base Product Number":"VIPER22","Voltage - Breakdown":"730V","Frequency - Switching":"60kHz","Operating Temperature":"-40°C ~ 150°C (TC)","Supplier Device Package":"8-DIP","Voltage - Supply (Vcc/Vdd)":"8V ~ 38V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/147a0ac8f744e2e76cf6bf7d98e26d03.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER22ADIP/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency of VIPER22ADIP?","answer":"The switching frequency is fixed at 60 kHz.
