ADP1046：隔离DC-DC副边应用控制器快速入门指南

rformed using the feedback ADCs, the digital loop filter, and the PWM block. The feedback ADCs use a multipath approach (patent pending). The ADP1046 combines a high speed, low resolution (fast and coarse) ADC with a low speed, high resolution (slow and accurate) ADC. Loop compensation is implemented using the digital filter. This proportional, integral, derivative (PID) filter is implemented in the digital domain to allow easy programming of filter char- acteristics, which is of great value in customizing and debugging designs.
