Problem
Many advanced electronic systems require DC power with minimal electromagnetic interference (EMI) and a small footprint, while also maintaining high efficiency and radiation tolerance. Traditional voltage regulators often struggle to meet all these requirements simultaneously, especially in harsh environments. Optocouplers, used for signal isolation, often suffer from low power transfer efficiency, limiting their effectiveness in demanding applications.
Solution
Polaris Semiconductor develops inductorless, switching-free DC buck and boost voltage regulators that combine the low noise and small footprint of linear regulators with the efficiency of switching regulators. Their patented device topology integrates an analog integrated circuit with high-efficiency optoelectronics, resulting in voltage regulators that are 100% RF silent, ultra-compact, highly efficient, and radiation tolerant. Additionally, Polaris Semiconductor's photovoltaic-output optocouplers provide high power transfer efficiency in a small footprint, enabling novel circuit concepts in applications with stringent noise and performance requirements, and are suitable for harsh radiation and temperature environments.
Target Audience
The primary target audience includes designers and manufacturers of cutting-edge electronic systems requiring low-noise, compact, and efficient DC power management, as well as those needing high-performance optocouplers for harsh environments.
