Introduction

The Vishay EDLCBU-3V3 Reference Design is a specialized backup power circuit developed by Vishay / Dale. This reference design leverages an EDLC (Electric Double Layer Capacitor), commonly known as a supercapacitor, to provide reliable energy storage and delivery for electronic systems during power interruptions.

Part Description

The Vishay EDLCBU-3V3 Reference Design is engineered as a supercapacitor-based backup power solution. It is capable of supplying high peak currents, making it suitable for applications that require immediate and robust power delivery when the main supply is interrupted. The design is optimized for low quiescent current operation, ensuring that energy is conserved when the backup system is not actively supplying power. This makes it highly efficient and ideal for battery-powered and energy-sensitive applications.

Applications

• Backup power for IoT nodes
• Emergency power for portable devices
• Power hold-up for embedded systems
• Data retention in memory modules during outages
• Short-term power for wireless sensors

Industries

• Consumer Electronics
• Industrial Automation
• Medical Devices
• Telecommunications
