This reference design uses the LM5155-Q1 boost controller to supply an 8-V, 4.5-A load and operates from a single-cell supercapacitor at the input. The converter can discharge a supercapacitor as low as 1.5 V to leverage as much as possible of the stored energy to open a car door in an emergency situtation, where the KL30 car battery voltage is not present.
Features
- Converter can operate from a single-cell supercapacitor and deliver 40-W output power.
- Operates down to 1.5-V input voltage enabling deep discharge of a supercapacitor.
- Design uses a non-synchronous controller
- Starts up from as low as 1.5 V.
- Design has been built and tested with test report being available.
