Overview
Description
This design uses an ISL85403 synchronous buck or boost-buck controller in the buck-boost configuration to extract power from a supercapacitor (as low as 0.1V).
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
- Reliable solution for battery and EDLC-based never-stop systems
