Abstract - This paper reports on the design and simulation of a current-programming controller for DC-DC switched power converters. The proposed analogue circuit allows custom integrated circuit (IC) implementation, which apart from a reduction in cost, mass and weight increases reliability. Current-mode VLSI analogue signal processing techniques are considered, resulting in a compact design suitable for high-frequency cycle-by-cycle control. The control circuitry has been laid-out in a standard 0.8mm CMOS technology. Post-layout simulation results for this monolithic controller show proper operation at 1Mhz switching frequency.
