| 6979987 | METHOD OF REGULATING AN OUTPUT VOLTAGE OF A POWER CONVERTER BY SENSING THE OUTPUT VOLTAGE DURING A FIRST TIME INTERVAL AND CALCULATING A NEXT CURRENT VALUE IN AN INDUCTOR SUFFICIENT TO BRING THE OUTPUT VOLTAGE TO A TARGET VOLTAGE WITHIN A SECOND TIME INTERVAL IMMEDIATELY FOLLOWING THE FIRST TIME INTERVAL AND VARYING A DUTY CYCLE OF A SWITCH DURING THE SECOND TIME INTERVAL The output voltage of a power converter is controlled by comparing the output voltage to a target output voltage during a first time interval and calculating an inductor current required in a second time interval immediately following the first time interval to incr... | 12/27/2005 |
| 6909266 | METHOD OF REGULATING AN OUTPUT VOLTAGE OF A POWER CONVERTER BY CALCULATING A CURRENT VALUE TO BE APPLIED TO AN INDUCTOR DURING A TIME INTERVAL IMMEDIATELY FOLLOWING A VOLTAGE SENSING TIME INTERVAL AND VARYING A DUTY CYCLE OF A SWITCH DURING THE TIME INTERVAL FOLLOWING THE VOLTAGE SENSING TIME INTERVAL The output voltage of a power converter is regulated by comparing the output voltage to a target output voltage during a first time interval and calculating an inductor current required in a second time interval immediately following the first time interval to incre... | 06/21/2005 |
| 6906502 | Method for regulating an output voltage of a power coverter A power converter output voltage regulation method in which sensed output voltages and sensed currents are stored in a memory during a plurality of time intervals. In each time interval the sensed output voltage and the sensed current is compared with the sensed out... | 06/14/2005 |
