The control circuit operates in the burst mode to regulate the average magnitude of the load current below the minimum rated current. During the burst mode, the control circuit regulates a peak magnitude of the load current to the minimum rated current during a first time period, and stops regulating the load current during a second time period, such that the average magnitude of the load current is below the minimum rated current. | 2015-11-05 |

20150318789 | SYSTEMS AND METHODS FOR SOURCE SWITCHING AND VOLTAGE GENERATION - System and method for regulating a power conversion system. An example system controller for regulating a power conversion system includes a first controller terminal associated with a first controller voltage and coupled to a first transistor terminal of a first transistor, the first transistor further including a second transistor terminal and a third transistor terminal, the second transistor terminal being coupled to a primary winding of a power conversion system, a second controller terminal associated with a second controller voltage and coupled to the third transistor terminal, and a third controller terminal associated with a third controller voltage. The first controller voltage is equal to a sum of the third controller voltage and a first voltage difference. The second controller voltage is equal to a sum of the third controller voltage and a second voltage difference. | 2015-11-05 |
20150318790 | METHOD AND APPARATUS FOR SYNCHRONOUS RECTIFIER OPERATION - A method and synchronous rectifier controller uses minimum off and on time blanking to avoid switching the switching transistor at incorrect times responsive to transients in the current sense signal. The minimum off time timer is commenced only when the current sense signal is above a reset threshold, and is reset when the current sense voltage falls below the reset threshold. Resetting the minimum off time timer in this manner avoids false starts of the minimum off time timer due to transients and allows the SRC to properly synchronize with the conduction and blocking phases of rectifier operation. | 2015-11-05 |
