Dynamic power management techniques and voltage converter architectures are described to provide a secure and efficient on-chip power delivery system. In aspects of the embodiments, converter-gating adaptively turns on and off individual stages of an interleaved switched-capacitor voltage converter based on workload information to improve voltage conversion efficiency. Converter-gating is further utilized as a countermeasure against side channel power analysis attacks by pseudo-randomly controlling converter activity. The embodiments also improve the response time of converters during transient load changes by adaptively configuring the conversion ratio of a switched capacitor (SC) voltage converter.
