Abstract :
The design and implementation of a CMOS analog integrated circuit that provides multi-mode control laws for high-frequency switching power converters is described. The general-purpose controller circuit is capable of implementing classical PWM control, current-mode control with compensating ramp, sliding-mode control and one-cycle control. The main building block within the controller architecture is the current conveyor. Additionally, the IC includes power MOSFETs and their drivers. Layout details for a CMOS 0.35 μm technology implementation are discussed.
