SYSTEM FOR CONTROLLING MODE CHANGES IN A VOLTAGE DOWN-CONVERTER

摘要

A voltage down-converter system, with a stand-by mode and an active mode, fo r a memory device with the following components. A charge node (68) is configured to receive a charge. A first transistor (54) has a first gate and the first transistor is configured to supply a load current to the memory device. A first switch (58) is coupled to the charge node and the first gate , the first switch being configured to apply the charge in the charge node to the first gate during transition from stand-by to active modes. A second transistor (66) is coupled to the first gate and configured to bias the firs t transistor to an inactive state during stand-by mode. A second switch (64) i s coupled to the first gate and the second transistor, the second switch being configured to apply a voltage difference at the second transistor to the fir st gate during the stand-by mode.
