EDLCBU-3V3 Reference Design

Vishay / Dale EDLCBU-3V3 Reference Design is a circuit that provides backup power using an EDLC supercapacitor as the energy storage element. It is engineered to supply high peak currents, with inductor current limits ranging from 1A to 5A. The EDLCBU-3V3 circuit can be used to supply photovoltaic-powered IoT nodes with energy during darkness. The design ensures reliable backup capability for devices that require immediate need of power during supply interruptions. Its low‑quiescent current operation maximizes energy efficiency and extends the readiness of the backup system. This design is used in handheld-equipment, portable devices with removable batteries, industrial sensors and actuators, energy storage for IoT devices, and graceful shutdown of embedded systems. Overall, the EDLCBU‑3V3 reference design offers a compact, efficient solution for maintaining uninterrupted functionality during brief power losses.
