During an initial period (Tramp), the controller provides a possibly smaller target current (Iramp) to reduce the system stress while the output voltage rises to a suitable value (InitVtar).

摘要： Apparatuses and methods of frequency hopping algorithms are described. One method monitors a signal on one or more electrodes of a sense network at a first operating frequency and detects noise in the signal at the first operating frequency. The method then switches to a second operating frequency, based on said detecting, for scanning the electrodes to detect a conductive object proximate to the plurality of electrodes, wherein a constant integration time is used for one half-period when scanning the electrodes at both the first and second operating frequencies.

摘要： To conserve power when regulating the output voltage (Vo) of a power converter, no adjustment is made to the converter's pulse width modulation times (Tp, Ts) even if the output voltage is off target (Vtar), provided that the output voltage does not change or is moving towards the target voltage. In some embodiments, the output voltage is not allowed to stay off target for more than a predetermined length of time. In some embodiments, the minimal adjustments are always large enough to overcome ringing (1004).
摘要翻译：为了在调节功率转换器的输出电压（Vo）时节省功率，即使输出电压为目标值（Vtar），也不会调整转换器的脉宽调制时间（Tp，Ts），只要输出电压不改变或正在朝目标电压移动。在一些实施例中，不允许输出电压停止超过预定时间长度的目标。在一些实施例中，最小调整总是足够大以克服振铃（1004）。

摘要： In a power converter, an input power source (98) is intermittently coupled to provide a current flow (Icoil) in consecutive cycles (T) to generate an output voltage (Vo). The coupling durations (Tp) are adjusted in conjunction with a cycle skip count (112CNT) which is the count of cycles in which no coupling occurs. In some embodiments, the adjustments are performed to keep the coupling durations near the maximum efficiency range (between TLOW and THIGH), and the skip count is adjusted at the same time to obtain the desired output voltage in the presence of load current variations. The coupling frequencies are kept in a desired range to avoid interference with other circuit elements.
摘要翻译：在功率转换器中，输入电源（98）间歇地耦合以在连续周期（T）中提供电流（Icoil）以产生输出电压（Vo）。耦合持续时间（Tp）与循环跳过计数（112 CNT）一起进行调整，循环跳跃计数是不发生耦合的循环计数。在一些实施例中，执行调整以将耦合持续时间保持在最大效率范围（TLOW和THIGH之间）附近，并且在负载电流变化存在的情况下同时调整跳跃计数以获得期望的输出电压。耦合频率保持在期望的范围以避免与其它电路元件的干扰。

摘要： A method for controlling a switching power converter provides an efficient algorithm for controlling the output voltage across loads that are relatively light with small transients. When the output voltage is at or below a predetermined first magnitude, a determination is made of the charge required for one or more pulses to increase the output voltage to a predetermined second magnitude which is greater than a target output voltage. Corrective action is taken to raise the output voltage to the second magnitude and the system takes no further corrective action until output voltage is determined to be at or below the first magnitude. The method is useful with synchronous or non-synchronous power converters of buck, boost, buck/boost or other topologies. The method further provides a simple means for determining the amount of charge removed from a battery.
摘要翻译：用于控制开关功率转换器的方法提供了一种有效的算法，用于控制跨越具有小瞬变的相对较轻的负载的输出电压。当输出电压处于或低于预定的第一幅度时，确定一个或多个脉冲所需的电荷将输出电压增加到大于目标输出电压的预定的第二幅度。采取纠正措施将输出电压提高到第二幅度，并且在确定输出电压等于或低于第一幅度之前，系统不再采取任何纠正措施。该方法对于降压，升压，降压/升压或其他拓扑的同步或非同步电源转换器非常有用。该方法还提供了用于确定从电池移除的电荷量的简单装置。
