20140092641 | SYNCHRONOUS RECTIFYING BUCK-BOOST CONVERTER - A synchronous rectifying buck-boost converter includes a controller, first and second transistors, an inductor and a capacitor. The controller is connected to the gates of the first and second transistors for controlling ON/OFF of the first and second transistors, and further controls the current of the inductor and charge/discharge of the capacitor. The first and second transistors connected in series are connected to the controller and the inductor. The inductor is connected to a first external power unit or a first external loading device. The drain of the first transistor is connected to a second external power unit or a second external loading device such that a low-voltage input power of the first external power unit is converted to a high-voltage output power or a high-voltage input power of the second external power unit is converted to a low-voltage output power. | 04-03-2014 |
20140218125 | DIGITAL PULSE WIDTH MODULATION CONTROLLER - A digital pulse width modulation controller includes a pulse width modulation controller, a selection unit having at least one selector, a comparison unit having at least one comparator, and a signal conversion unit having at least one digital-to-analog converter. The digital-to-analog converter generates a reference current and/or voltage. The comparator receives the reference current and/or voltage, and performs a comparison operation to generate a comparison signal based on a feedback signal. The selector selects one selection signal to input into the pulse width modulation controller, which receives other parameters set by a user or the system at the same time so as to control characteristics of the digital pulse width modulation signals, thereby improving the electric properties of a loading circuit. | 08-07-2014 |
