Abstract:

A hybrid voltage-mode hysteretic boost converter is introduced in this work. The implemented control topology is practically self-stabilized due to the introduction of a current-limiting loop. A full range inductor current sensor and a hysteretic comparator are used to realize the current-limiting loop. A zero current detector is also implemented to enable a seamless transition from continuous to discontinuous conduction mode. The hybrid voltage-mode hysteretic boost converter is designed in a 0.5-μm CMOS process for an input voltage range of 3.2-4.2 V. The converter regulates to an output voltage of 5 V while driving a load range of 20-200 mA. A minimum efficiency of 93% is achieved across the full operating input voltage and load current ranges.
