It cleverly combines a dedicated current-mode PWM controller with a rugged, high-voltage avalanche power MOSFET all within a single standard DIP-8 package.\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, the VIPer22A is incredibly popular for offline power conversion. It features a wide VDD voltage range of 9V to 38V, a fixed 60 kHz switching frequency, and built-in protections against over-temperature, over-voltage, and over-current. Whether you are a hardware engineer designing a custom standby power module or a technician repairing a consumer appliance power board, this IC provides a highly reliable, low-component-count solution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e viper22a ic, stmicroelectronics viper22a, smps controller ic, dip-8 power ic, offline converter chip, dvd player power ic.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e STMicroelectronics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e VIPer22A (VIPER22ADIP-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e 8-Pin DIP (Through-hole)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrain Voltage (Vds):\u003c\/strong\u003e Up to 730V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVDD Supply Voltage:\u003c\/strong\u003e 9V to 38V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitching Frequency:\u003c\/strong\u003e Fixed 60 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Power Capability:\u003c\/strong\u003e 20W (European mains 195-265 Vac) \/ 12W (Wide range 85-265 Vac)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Protections:\u003c\/strong\u003e Thermal shutdown, over-voltage, and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eDatasheet\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/viper22a-e_5d179e87-e663-42df-8203-9d16ebb2886e.pdf?v=1784889132\" target=\"_blank\" rel=\"noopener\"\u003eDownload VIPer22A (STMicroelectronics) Datasheet PDF\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsumer Appliance Repair:\u003c\/strong\u003e A direct replacement component for repairing burnt-out power supply boards in DVD players, set-top boxes, and satellite receivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby Power Supplies:\u003c\/strong\u003e Designing highly efficient auxiliary and standby AC-DC power supplies for heavy machinery or ATX power units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED Drivers:\u003c\/strong\u003e Acting as the primary switching regulator in compact, low-power constant-current LED lighting drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Adapters:\u003c\/strong\u003e Building custom, low-component-count wall plug adapters for microcontroller projects and consumer electronics.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the VIPer22A replace a burnt IC in my set-top box?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The VIPer22A is one of the most common SMPS controller ICs found in consumer electronics like DVD players, set-top boxes, and DTH receivers. Just ensure the original chip is explicitly marked VIPer22A and uses the same DIP-8 package.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this IC require an external oscillator crystal?\u003c\/strong\u003e\u003cbr\u003eA: No, the VIPer22A features an internal oscillator that is factory-fixed at 60 kHz, significantly reducing the external component count needed to build a working power supply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a heatsink for this DIP-8 package?\u003c\/strong\u003e\u003cbr\u003eA: Typically, no. For low-power applications (under 12W on universal mains), the thermal dissipation of the DIP-8 package itself is sufficient, combined with the IC's built-in thermal shutdown protection which prevents catastrophic overheating.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × VIPer22A SMPS Primary Switcher IC (STMicroelectronics) – DIP-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ST Microelectronics","offers":[{"title":"Default Title","offer_id":48382657593582,"sku":"INC-01699","price":29.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/ICVIPPER22AST.jpg?v=1784889443","url":"https:\/\/www.tomsonelectronics.com\/products\/viper22a-smps-primary-switcher-ic-stmicroelectronics-dip-8","provider":"Tomson Electronics ","version":"1.0","type":"link"}
