| 20080204290 | PROGRAMMABLE ANALOG-TO-DIGITAL CONVERTER FOR LOW-POWER DC-DC SMPS - A voltage-to-time based windowed analog-to-digital converter (ADC) can have programmable reference voltage, conversion time, and accuracy of voltage regulation. The ADC can be fully implemented on a small silicon area and is suitable for implementation in various integrated digital controllers for high-frequency low-power switch-mode power supplies (SMPS). The programmable characteristics can be achieved through the utilization of the inherent averaging effect of the delay line or of the other voltage-to-time conversion structures and through the adjustments of delay cells' propagation times or the effective voltage-to-time conversion ratio in alternative structures. | 08-28-2008 |
| 20080204160 | UNIVERSAL AND FAULT-TOLERANT MULTIPHASE DIGITAL PWM CONTROLLER FOR HIGH-FREQUENCY DC-DC CONVERTERS - A multiphase hybrid digital pulse width modulator can comprise a counter that is selectable between at least two different numbers of states to indicate a first portion of a switching period. Unclocked logic can indicate a second portion of the switching period. The unclocked logic can include a delay line. | 08-28-2008 |
