                   Power MOSFET Section:
                   The section Includes DQ1…DQ18, DL1…DL7, and R, C. The output VCORE depends
                   on input VIN and control gate UG1, LG1 of high side MOSFET DQ1 and low side

                   MOSFET DQ4, DQ7. The control gate must be a waveform input from PWM drive.
                   The sensed current ISEN1 …ISEN6 and PHASE1…PHASE 6 will feedback to PWM
                   controller , the sensed current is used for channel current balancing, over current
                   protection, and droop regulation.
