PRODUCT OVERVIEW

Volterra’s core products are integrated voltage regulator semiconductors and scalable voltage regulator semiconductor chipsets that are used to transform, regulate, deliver and monitor the power consumed by digital semiconductors, such as microprocessors, graphics processors, digital signal processors and memory. Volterra’s products integrate multiple power, analog and digital functions that are generally performed by numerous discrete components in conventional solutions to maximize performance and minimize size.

There are two families of integrated voltage regulator semiconductors, VT100 and VT200, and one family of scalable voltage regulator semiconductor chipsets, VT1000. We have developed over 35 products across our three major product families. We classify our product families by specifications such as input voltage and output voltage, both measured in Volts, and maximum current, measured in Amperes or Amps. We continually develop new generations of our products to improve product performance and features while reducing system size and cost.

The following table describes Volterra’s product families, product family descriptions and representative applications.
