The stringent requirements on both the control bandwidth and the supply standby current make it tough to design the IC controllers for the v-core converters in future computer applications. The effects of the non-ideal characteristics of the finite gain-bandwidth product and non-zero output impedance of an operational amplifier (OP) are investigated for such a purpose. The results show surprising...
Peak current control (PCC) can be used to achieve adaptive voltage positioning (AVP) in DC power converters for CPU power applications. However, PCC is seldom used because of the problem with output voltage offset from the target load line. A novel high-gain PCC (HGPCC) AVP scheme was recently reported to correct the aforementioned offset problem while retaining the advantages of PCC, such as easy...
