The VIPerPlus series of high-voltage converters combines an 800 V avalanche-rugged MOSFET with a leading-edge PWM controller. With extremely low total standby consumption (less than 4 mW at 230 VAC) and high efficiency over a wide load range, VIPerPlus devices enable SMPS designs meeting the most demanding energy-saving regulations with enhanced reliability and scalability, and can cut in half the component count.
- The VIPer0P is characterized by a unique zero-power mode and is ideal for all SMPS up to 7 W with a wide input voltage range. The device also integrates an error amplifier and a logic-level MOSFET, simplifying the design of compact and ultra-low consumption SMPS (buck or flyback) with a 5 V output voltage.
- The VIPerPlus series 1 integrates an error amplifier and a logic-level MOSFET that makes it possible to build a simple and ultra-low consumption SMPS (buck, buck-boost converter or flyback) with a 5 V output voltage. A unique overvoltage protection and the 18 VDC drain voltage start up make it robust and reliable.
- The VIPerPlus series 5 provides the highest efficiency using a quasi-resonant topology.
- The VIPerPlus series 6 integrates an error amplifier to meet the most advanced SMPS requirements, reducing the part count.
- The VIPerPlus series 7 features brown out and overvoltage protection for improved reliability.
- The VIPerPlus series 8 offers peak power capability to sustain 1 to 2 second overloads for enhanced robustness.

VIPer11 enables ultra-low consumption SMPS for 5-30 V output and ultra-wide range input voltage
Integrating an 800 V avalanche-rugged logic-level MOSFET with PWM current-mode control and multiple protection circuits, the VIPer11 high-voltage converter enables designers to create a simple and ultra-low consumption SMPS in flyback, buck, or buck-boost configuration with a 5 V output. It is ideal for low-power applications in home appliances, building, lighting, motion control as well as small industrial and consumer applications. Its integrated high-voltage start-up and sense-FET, error amplifier, and oscillator with jitter minimizes the number of external components required to design a complete application.
