The is a Power Supply that integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric, solar or magnetic transducers. An ultralow quiescent current undervoltage lockout UVLO mode with a 16V rising threshold enables efficient energy extraction from sources with high open circuit voltages. This energy is transferred from the input capacitor to the output via a high efficiency synchronous buck regulator. The buck features a sleep state that minimizes both input and output quiescent currents while in regulation. Suit Li-Ion and LiFePO4 batteries as well as supercapacitors.
