The 60 kHz fixed switching frequency keeps transformer core size manageable. The internal power MOSFET is rated for a 14.5 V startup threshold and operates with a Vcc supply range of 9 V to 38 V, which covers the typical bias rail from an auxiliary winding. ## Integrated protection — fewer external components The VIPER12ADIP integrates current limiting, over-temperature shutdown, and over-voltage protection. This reduces the external component count to a bridge rectifier, input bulk capacitor, transformer, output diode, and a few passives.","metaTitle":"STMicroelectronics VIPER12ADIP Offline Switcher, 13 W, 730 V","metaDescription":"ST VIPER12ADIP non-isolated offline switching regulator, 13 W output, 730 V breakdown, 60 kHz fixed frequency.","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":"-","Duty Cycle":"-","Mounting Type":"Through Hole","Power (Watts)":"13 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":"Non-Isolated","Internal Switch(s)":"Yes","Voltage - Start Up":"14.5 V","Base Product Number":"VIPER12","Voltage - Breakdown":"730V","Frequency - Switching":"60kHz","Operating Temperature":"-40°C ~ 150°C (TC)","Supplier Device Package":"8-DIP","Voltage - Supply (Vcc/Vdd)":"9V ~ 38V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5bcc9c5b210192439050849cb8a32286.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VIPER12ADIP/alternatives.json"},"ai":{"faq":[{"question":"Is VIPER12ADIP obsolete?","answer":"Yes, the VIPER12ADIP is listed as obsolete.
