摘要： In one embodiment, a method of forming a multi-channel power supply controller includes forming a plurality of channels configured to regulate an output voltage between first and second values, configuring the controller to select a channel that has a lowest current value and initiate forming a drive signal for that channel responsively to the output voltage having a value that is less than the first value, configuring a reset circuit for each channel to terminate the respective drive signal responsively to at least the output voltage having a value greater than the first value.

摘要： A switched noise filter circuit for DC-DC converters which use the instantaneous output voltage to establish the converter's duty ratio. The converter cycles the switching element on and off for time intervals Ton and Toff, respectively. A switching control circuit includes a filter capacitance connected between the feedback node and ground, and a comparator which compares a feedback voltage Vfb with a fixed voltage Vref; at least one of Ton and Toff is a “modulated” interval which is terminated when Vfb crosses Vref due to the discharge of the filter capacitance. A switched noise filter circuit applies an offset voltage to Vfb during at least one of Ton and Toff, with the offset voltage disconnected from Vfb by the beginning of the modulated interval or shortly thereafter. When the offset voltage is properly applied, the effect of extraneous electromagnetic noise coupled into Vfb is reduced.

摘要： A digital blanking circuit allows a first digital input signal transition to be passed on to a following stage, but prohibits the passing of subsequent transitions for a predetermined blanking interval. One embodiment of the present invention employs rising edge and falling edge latches, the inputs of which receive the digital input signal and the outputs of which are connected to a two-to-one multiplexer. The mux output is connected to a blanking interval circuit, which is triggered to begin timing a blanking interval by a multiplexer output transition. The blanking interval circuit provides outputs which control the latches and selects the latch output to be transferred to the multiplexer output such that the multiplexer output is prevented from transitioning during a blanking interval. An “adaptive” blanking circuit is also described in which the blanking interval is terminated when the transition which triggered the start of the blanking interval propagates through an entire signal path, such that the blanking interval is automatically adjusted to be the same as the signal path delay.

摘要： A method and circuit enable a voltage regulator to employ the smallest possible output capacitor that allows the regulator's output voltage to be maintained within specified boundaries for large bidirectional step changes in load current. This is achieved with a technique referred to as “optimal voltage positioning”, which keeps the output voltage within the specified boundaries while employing an output capacitor which has a combination of the largest possible equivalent series resistance (ESR) and lowest possible capacitance that ensures that the peak voltage deviation for a step change in load current is no greater than the maximum allowed. The invention can be used with regulators subject to design requirements that specify a minimum time Tmin between load transients, and with those for which no Tmin is specified. When no Tmin is specified, optimal voltage positioning is achieved by compensating the regulator to ensure a response that is flat after the occurrence of the peak deviation, which enables the output voltage to remain within specified limits regardless of how quickly load transients occur. Another embodiment enables the power consumption of the device being powered by the regulator to be reduced under certain circumstances, while still employing the smallest possible output capacitor that allows the regulator's output voltage to be maintained within specified boundaries. The invention is applicable to both switching and linear voltage regulators.
摘要翻译：一种方法和电路使得电压调节器能够使用尽可能小的输出电容器，该电容器允许将稳压器的输出电压保持在规定的边界内以实现负载电流的大的双向步进变化。这是通过称为“最佳电压定位”的技术实现的，其将输出电压保持在指定边界内，同时采用具有最大可能等效串联电阻（ESR）和最小可能电容的组合的输出电容器，其确保负载电流阶跃变化的峰值电压偏差不大于允许的最大值。本发明可以根据规定负载瞬变之间的最小时间Tmin以及规定没有Tmin的设计要求进行调节。当没有指定Tmin时，通过补偿调节器来实现最佳电压定位，以确保峰值偏差发生后的平坦响应，这使得输出电压能够保持在指定的限制内，而不管负载瞬变发生的速度如何。另一个实施例使得在某些情况下能够减小由调节器供电的装置的功耗，同时仍然采用允许调节器的输出电压保持在指定边界内的尽可能小的输出电容器。本发明适用于开关和线性稳压器。
