Isolation and Voltage Regulation Circuit

Abstract

The disclosure relates to an isolation and voltage regulation circuit for an electrochemical power source, the circuit comprising: an input terminal (202) for coupling to the power source and receiving an input voltage (Vin) from the power source; an output terminal (204) for coupling to a load; a diode circuit (206) connected between the input terminal and the output terminal; a diode controller (208) configured to control electrical conduction through the diode circuit between the input terminal and the output terminal, the diode controller having a first controller input (210) coupled to the output terminal and a second controller input (212); and a reference controller (220) configured to set a voltage at the second controller input (212) in accordance with a comparison between the input voltage (Vin) and a reference voltage (Vref).

Dependencies are inferred from the claim text.
