Abstract :
This paper presents a high efficiency digital controller for a switching type DC-DC converter with excellent static and dynamic performance. This digital PWM controller integrates a PID-like control mechanism and a new predictive interpolation technique to guarantee large signal stability and fast dynamic response. To support the proposed control scheme, an ADC structure that can sequentially sample the output level is proposed. All the circuit architectures are for low power thus achieve the maximum 96% power efficiency with 0.35 W output.
