Part Number: LMG1205
The module lmg 1205, used in a DC-DC module, malfuntions in the level of PCB. The phenomenon is that the supply voltage of both the lmg1205 and the input cannot be up to the expected values. In my design, the input voltage is 84V, but it turns out only 0.6~0.9V able to add to the circuit. What mistakes may I had made? The PCB or the circuit itself that has been stimulated in LT spice several times? It is improtant to note that during the stimulation, there are some points when the speed of stimulation gets really slowly, but eventually the output voltage obtain the ideal value. If these ponits account for the failure?
