On-chip switched-capacitor (SC) converters have gained increasing popularity for this application due to their ease of integration using only transistors and capacitors readily available in the chosen technologies [1-6]. Historically, on-chip SC converters have been perceived as low power converters with output powers below 150mW [1-5]. However, the scalability of output
