VSMC’s technology based on 6 patents pending on the Control Methodology for Adaptive Digital Control.  

Our Adaptive Amplitude Slew-rate Pulse Width Modulation (ASPWM) could produce a precise level ofvoltage regulation which is required for today and future battery-operated portable devices.  

Our Digital Controlled technology is also applied in many fields such as thermal sensor, engine controlled,...  

Unique IC designs allows readily detection and monitor of any infringement.

 We are seeking worldwide patent coverage.
