[0026] In order to describe the technical content of the present invention more clearly, further description will be given below with reference to specific embodiments.
[0027] see Figure 2 to Figure 6 As shown, the structure of the DC-DC converter with line loss compensation described in the present invention is as follows figure 2 , its main structure is similar to the current mainstream DC-DC converters in current control mode. In addition to various protection modules, the control circuit is mainly composed of a reference module, an error amplifier, a comparator, a control module, a first switch tube, and a second switch tube. It is composed of the first driver stage, the second driver stage, the bootstrap module, the current amplifier, the oscillator and the slope compensation module, and the SW terminal of the control circuit and the filter circuit (see image 3 , in which the inductor L1 and the capacitor C1 play a filtering role, and the role is to filter the switc...
