HYSTERETIC CHARGER FOR ENERGY HARVESTER DEVICES

摘要

A hysteretic converter includes an inductor coupled between a source of voltage and a switch node. A low side switch is coupled between the switch node and a reference voltage. A high side switch is coupled between the switch node and the output of the converter. A driver controls the low side and high side switches, wherein the low side switch is turned on until the input current rises to a predetermined set point, the predetermined setpoint can be adapted to input current from the source of voltage.
