摘要: | This paper proposes a solid-duty-control (SDC) technique for application in boost converters to maintain a constant duty value and reduce dip voltage during load transient periods. Fast transient response was also achieved because of the variable transient enhancement controller. The proposed SDC technique can provide a stable and regulated output for edge-lit light-emitting diode backlight systems. This converter was used in a 0.25-mu m CMOS process. Experimental results show that compared with a conventional design without a fast transient technique, the proposed approach yields about 30% and 80% improvement in undershoot voltage and recovery time, respectively, as load current changes from 50 to 250 mA. |
