Capacitive sensing enabled switch mode power supply and data transfer

摘要: A microchip for control of a switch mode power supply (SMPS), with said also having the ability to measure capacitance an electrode or sense plate structure structures, and use low power, microchip, distinct from main energy path via SMPS load. The may transition between active state inactive state, measured used determine condition transition. In only draws operate its capacitive sensing circuitry, leading significant standby losses decrease compared prior art. Further teachings by present invention include based data transfer, universal charging platforms mobile devices, noise immunity enhancements, various lighting embodiments as well operation improvements.
