Patent number: 8629660Abstract: A boost regulator is provided that has increased efficiency. The increased efficiency is provided by incorporating a sensing circuit that senses when the current in the boost regulator's inductor is near zero or when the voltage at its switching node is near zero or virtual ground. A switching signal is provided to the boost regulator's switching transistor when the near zero current or voltage is sensed. Switching at the near zero current or voltage moment (the “critical conduction moment”) helps to eliminate or minimize the power loss associated with switching the transistor at a time other than during the critical conduction moment.Type: GrantFiled: January 29, 2010Date of Patent: January 14, 2014Assignee: Maxim Integrated Products, Inc.Inventor: Mehmet K.
