METHOD AND NETWORK FOR PROVIDING FIXED FREQUENCY FOR DC-DC HYSTERETIC CONTROL BUCK CONVERTER

摘要

A method, circuits and networks have been provided for improved stable dynamic voltage regulation. The circuits include a tunable hysteretic window module, a buck converter and a voltage regulation module. The tunable hysteretic window module, the buck converter and the voltage regulation module are coupled such that a fixed switching frequency can be achieved. The tunable hysteretic window module includes a tuning module and a hysteretic window comparator module and a feedback network is formed connecting the voltage regulation module and the hysteretic window comparator module to achieve improved voltage regulation.
