A 100μA Digital Controller with Transient Enhancement
for Dynamic Voltage
Output Switching-type DC-DC Converter
Abstract
| This paper presents a high efficiency digital controller for a switching type DC-DC converter with excellent static and dynamic performance. The 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 circuits architectures are for low power thus achieve the maximum 96% power efficiency with 0.35W output. |
