Capacitive DC-DC converter saves up to 90% BOM cost
Nexperia today announced an expansion of its range of power ICs with Energy Harvesting solutions to simplify and improve performance of low-power Internet of Things (IoT) and other embedded applications. The NEH2000BY is a high performance Power Management Integrated Circuit (PMIC) that recharges a battery or storage capacitor using energy harvested from environmental sources such as light (which can be harvested using a photovoltaic cell). As a result, Nexperia's NEH2000BY will enable the development of smaller, more environmentally friendly, self-powered electronic devices. Additionally, this energy harvesting solution can help mitigate the environmental impact of the billions of batteries that are produced and disposed of each year.
Nexperia's NEH2000BY PMIC greatly facilitates the design of energy harvesting solutions that can be up to 20 times smaller than other competitive offerings and do not require manual optimization for individual applications. In addition, the PMIC has been designed without inductors, which simplifies PCB layout and significantly reduces BOM and board size, with a mounting area of 12mm².
To achieve maximum conversion efficiency, energy harvesting solutions must be able to adapt to fluctuations in the ambient power source. The NEH2000BY performs Maximum Power Point Tracking (MPPT), an adaptive algorithm to optimize the way it transfers harvested energy and achieve optimum average conversion efficiency of up to 80%. This unique MPPT algorithm combines speed and precision, allowing the PMIC to adapt to environmental changes in less than a second. This is significantly faster than any other solution currently available and maximizes the amount of energy captured over the course of a day, vastly expanding the number of application areas. Additionally, with its self-optimizing feature and ability to run autonomously without the need for pre-programming, the NEH2000BY makes it easy for designers to power devices with ambient power.
Nexperia's energy harvesting solutions enable the economical harvesting of energy from various environmental sources in applications that consume up to several milliwatts of power, including wireless IoT nodes, wearable smart tags, and electronic shelf labels.
Dan Jensen, Managing Director of Nexperia's Logic and Analog ICs Business Group, adds: “The NEH2000BY is cost-effective, easy-to-use and compact, which will enable the adoption of power harvesting in a wide range of use cases. . By eliminating the need to change batteries in these applications, the NEH2000BY will significantly reduce the amount of hazardous waste produced, with enormous benefits for the environment."
The NEH2000BY is available in a 16-pin, 3mm × 3mm QFN package, and operates between -40°C to +85°C.
