Energy Harvesting Reference Design Solution for Ultra Low Power Boost Converter IC

This reference design is an ultra low power boost converter for energy harvesting Applications. This solution is programmed from the factory for settings compatible with most MCU’s and 3V coin cell batteries. The design is programmed to deliver a 3.1VDC maximum voltage (OV) for charging the storage element and the under voltage is programmed to 2.2VDC. The VBAT_OK indication toggles high when VSTOR ramps up at 2.8VDC and when VSTOR ramps down to 2.4VDC.
