|Article: MPS Smart Ramp Technology - A Solution to Voltage Change-Induced Audible Noise||
Audible noise in voltage regulator (VR) systems has been a problem for a very long time now. In the PC industry, the issue became more pronounced as the CPU became responsible for significant and repetitive voltage changes that induced noise through the VR. Those voltage changes, along with the physical properties of ceramic capacitors and the motherboard, produce an audible noise problem for the PC manufacturer with no good solutions so far. MPS had addressed the voltage change-induced audible noise issue by introducing MPS Smart-Ramp technology.
