摘要： An object of this disclosure is to implement a Buck, Boost, or other switching converter, with a circuit to supply a reference voltage and Adaptive Voltage Positioning (AVP), by means of a servo and programmable load regulation. The reference voltage is modified, achieving a high DC gain, using a servo to remove any DC offset at the output of the switching converter. The correction implemented by the servo is measured, and a programmable fraction of the correction is injected back on either the reference voltage or the output feedback voltage. To accomplish at least one of these objects, a Buck, Boost, or other switching converter is implemented, consisting of an output stage driven by switching logic, with a servo configured between the reference voltage and the control loops of the Buck converter. The AVP function is implemented on either the reference voltage or output feedback voltage.

摘要： A servo block in a Buck, Boost, or switching converter allows a positive offset to be applied to the DAC voltage. In a typical switching converter application, the load will have a positive current, sourced from the switching converter to ground through the load. This will cause the output voltage of the switching converter to fall with the output impedance. The servo block corrects the output voltage by adjusting the DAC voltage upwards. In the case where current is forced back into the switching converter, causing the output voltage to rise, the servo block will have affect. The behavior of the servo block is desirable as it reduces the negative affect the servo block may have on load transients occurring when the switching converter is in over voltage. In particular, the idea of shifting the DAC voltage for several different loops with a single servo block is disclosed. This scheme is particularly effective for a switching converter design, allowing the slow loop integrator and fast existing switching converter control loops to be considered almost independently.

摘要翻译：降压，升压或开关转换器中的伺服块允许将正偏移应用于DAC电压。在典型的开关转换器应用中，负载将具有正电流，从开关转换器通过负载接地。这将导致开关转换器的输出电压随输出阻抗而下降。伺服模块通过向上调整DAC电压来校正输出电压。在电流被强制回到开关转换器的情况下，使输出电压升高，伺服块将产生影响。伺服块的行为是期望的，因为它减少了当开关转换器处于过电压时，伺服块可能对负载瞬变产生的负面影响。具体地，公开了通过单个伺服块来移动几个不同回路的DAC电压的想法。该方案对于开关转换器设计特别有效，允许慢环积分器和快速存在的开关转换器控制回路被几乎独立地考虑。
