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.
