Hello, I am working on wearable medical sensor device, where the supercapacitor based power supply is planned. The supercapacitor charging system is not yet designed, so I am looking for advice.
Since the USB port is included on device, I am looking for simple approach to charge supercapacitor (5V 5F) via USB power lines.
1. Question: Is appropriate approach to charge supercapacitor via TPD3S014 from USB port (PC or phone charger)?
2. Additional question: I would like to hear the suggestions about supercapacitor's output voltage regulation.
2.5 V (< 80 mA) output voltage is required. In order to use supecapacitor efficiently the boost or buck/boost converter should be used. I prefer to use TPS61200DRC due the low operationg input voltage.
