Overview
Description
In this reference design, a supercapacitor is used as a backup power supply. The board allows for quick evaluation of the ISL85403 buck/boost controller in the two-stage boost buck configuration and the ISL9001A low dropout linear regulator. It is a cost-effective design for low-power, wide input voltage range point-of-load applications where both stepping up and stepping down voltage capabilities are required.
Features
- The ISL85403 controller can fully extract the power of the supercapacitor
- Buck-boost with electrical double-layer capacitor (EDLC) backup with one ISL85403
- Quiescent current is only 300µA
- Very high discharge efficiency
- Reliable solution for battery and EDLC-based never-stop systems
