This paper presents a novel low power boost converter designed and optimized to operate with a minimum input voltage as low as 250mV, which is the typical voltage range of novel micro energy sources. The low power budget of such energy sources (at most few hundreds of μWs) mandates the adoption of very efficient circuit solutions. The realized PCB prototype provides a regulated maximum output voltage 3.3V with 70% maximum efficiency, thus making the proposed converter topology very attractive for low power application power supply. Noticeably the converter operates without any external power supply of the control logic.

Abstract

This paper presents a novel low power boost converter designed and optimized to operate with a minimum input voltage as low as 250mV, which is the typical voltage range of novel micro energy sources. The low power budget of such energy sources (at most few hundreds of μWs) mandates the adoption of very efficient circuit solutions. The realized PCB prototype provides a regulated maximum output voltage 3.3V with 70% maximum efficiency, thus making the proposed converter topology very attractive for low power application power supply. Noticeably the converter operates without any external power supply of the control logic.
