| 20080231115 | Multiple-Output DC-DC Converter - The invention relates to a DC/DC converter design. The converter requires only one single inductor to draw energy from one input source and distribute it to more than one outputs, employing Flexible-Order Power-Distributive Control (FOPDC). It include a single inductor, a number of power switches, comparators, only one error amplifier, a detecting circuit and a control block to regulate outputs. This converter can correctly regulate multiple outputs with fast transient response, low cross regulation, and effective switching frequency for each output. It can work in both discontinuous conduction mode (DCM) and continuous conduction mode (CCM). Moreover, with FOPDC, future output extension is simple, making a shorter time-to-market process for next versions of the converter. The design can be applied to different types of DC-DC converter. | 09-25-2008 |
