Key features include:
- Optimizes efficient conversion of harvested limited power down to 10 µW – 1-mW range with best in class sub-µW operation losses
- Programmable maximum power point tracking with open circuit voltage sensing ensures most energy extracted from harvester
- 250-nA quiescent current in deep-sleep mode prolongs operation time with minimized loss of ambient energy
- Integrated charge pump circuitry enables cold start at 380-mV input voltage with no energy on system node
Harnessing “indoor” ambient light as a viable power source has become a growing trend in wireless sensor network applications worldwide.
