20080247196 | Switched Mode Power Supply With Synchronous Rectifier - In a controller (CC | 10-09-2008 |
20080278982 | Power Factor Correction Boost Circuit - The invention relates to a power factor controller for use in a power factor correction circuit. The power factor controller comprises a first input (VinSense) for receiving an input voltage (Vin) of the power factor correction circuit, a second input (VoSense) for receiving an output voltage (Vout) of the power factor correction circuit, and a controllable current source (VCCI) having a control input coupled to the first input, and a current supply output coupled to the second input, wherein said controllable current source (VCCI) sources a current to the second input (VoSense) that is inversely proportional to the input voltage. | 11-13-2008 |
20110026277 | DRIVING CIRCUIT - A driving circuit for an opto-coupler comprising a switched mode regulator configured to convert a first voltage to a second voltage, the switched mode regulator operable in accordance with a control signal ( | 02-03-2011 |
20120327691 | SWITCHED MODE POWER SUPPLY - A power supply has over power protection based on the same signal as used by the feedback path for controlling the switching of the power supply. This means that no additional signal needs to be supplied to the control circuit to implement mains over protection. | 12-27-2012 |
