Capacitor-based Power Conversion

Our Story:
pSemi’s journey in capacitor-based power conversion began with the acquisition of the pioneering MIT start-up Arctic Sand in 2017. Arctic Sand understood that using capacitive energy transfer, rather than more traditional inductive switching converters, would establish higher power conversion efficiency in low-profile form factors previously thought unobtainable.

pSemi has continuously developed architectural innovation combined with the latest advances in Murata capacitor technology. This combination has resulted in the release of a wide range of industry-leading products and over 250 patents….and growing!

Unleashing the Power of Capacitive Energy Transfer – the Next Chapter

pSemi capacitor-based power conversion technology is now becoming the de-facto standard in multiple applications from mobile smartphones to networking and telecoms. This leadership is evident in the compatibility with standards implementations, such as USB programmable power supply (USB_PPS) and Qi wireless charging implementations, where charge pump technology provides significant efficiency and size benefits when powered from a regulated voltage source.

pSemi offers industry-leading products, including charge pump switched capacitor converters, 2-stage buck and boost (LED drivers) converters, and multi-level converters.

Charge Pump Switched Capacitor Converters​

pSemi’s novel charge pump architectures use a small output inductance, acting as a constant current source, to eliminate or reduce capacitive switching redistribution losses. This lossless or adiabatic technique enables higher conversion efficiencies with 20-30% reduction in flying capacitor size and reduced EMI emissions. 

Charge pump, switched capacitor
  • Divider ratios: 4, 3, and 2 up to 160W
  • Ultra-high conversion efficiencies—up to 99% peak
  • 48V, 54V, and 12V input range for the networking and data center market
  • 4S, 3S, and 2S battery input range for the mobile market
  • Proven track record in top-tier smartphones

2-Stage Regulators

The 2-stage architecture combines charge pump technology with a switching regulator to improve power conversion efficiency in low-profile applications. In the 2-stage buck converter, a charge pump divider is followed by a buck regulator. In the 2-stage boost converter for LED driver applications, a boost converter is followed by a capacitive multiplier.

2-stage buck architecture—a charge pump divider followed by a buck regulator
  • 2-stage buck regulator available from 12V input (module solutions) and 3.3V input solutions
  • 2-stage boost LED drivers available from 1S–3S input ranges
  • Targeting low-profile, high-efficiency power delivery
2-Stage Buck Regulators

Multi-level Buck Regulators

At pSemi, we are applying our extensive knowledge and experience in switching capacitor technology to the development of leading-edge, multi-level architectures. 3- and 4-level conversion achieves high efficiency power conversion while reducing the height and size of the output inductor to provide a low-profile solution.

Multi-level buck converter with N-levels of conversion
  • High efficiency for low-profile (< 1 mm) applications such as smartphones and tablets
  • Ideal for 1S battery and fast-charging applications
  • Wide-range input capability for powering from USB and wireless charging sources
