CC-100 Power Optimizer

The CC-100 Power Optimizer is an integral part of CurrentRF's energy harvesting technology, primarily featured in products like PowerStic and Exodus devices. This compact IC, measuring 1.4mm x 1.4mm, is designed to be embedded in the ground lead of DC-Link capacitors, offering significant energy savings. By harvesting, inverting, and recycling a portion of the normally wasted current, the CC-100 Power Optimizer effectively cancels a part of the incoming current impulse. This feedback mechanism reduces battery charging requirements, extending the driving range of electric vehicles by up to 10%, making it an economical solution for manufacturers striving to enhance efficiency without considerable expense. This IP is particularly effective in electric and hydrogen fuel cell vehicles, where it helps to alleviate deep discharges of key capacitors in the vehicle's electrical system. As a result, it aids in reducing the recharge demand, consequent battery drain, and thus extends not only the longevity of the battery system but also the range per charge. The CC-100 Power Optimizer supports manufacturers’ designs by decreasing power consumption while improving the overall eco-friendliness of vehicle technology. Its implementation is particularly advantageous in high-voltage systems, where interfacing with cable shields and disconnecting waste currents can lead to substantial performance enhancements. The CC-100 IC stands as a testament to how innovative design in power management can lead to substantial energy savings and operational improvements.

PowerPad Dynamic Power Reduction

CurrentRF's PowerPad Dynamic Power Reduction is a groundbreaking IP designed to significantly reduce power consumption in integrated circuits without increasing area usage. By overlaying power and ground bondpads, the PowerPad enhances the energy efficiency of ICs by dynamically adjusting power flow, effectively harvesting unused dynamic power and channeling it back into the circuit. This results not only in saving significant kilowatt-hours of energy but also in extending system and battery life. Integrated into existing structures with almost zero area expansion, the PowerPad sets a benchmark for energy conservation in chip design, making it particularly advantageous for applications where space is a constrained resource. It is particularly tailored for use in environments such as data centers and cloud computing where power efficiency correlates directly with operational cost savings and environmental impact. The technology inherent to the PowerPad also supports the enhancement of signal integrity by reducing EMI effects and thus bolstering the overall reliability of digital systems. This dual capability of reducing costs while increasing performance ensures its standing as a vital component in the toolkit of power-conscious designers.
