Hi, I am using LT3751 as capacitor charger. It works with LTC3126 as voltage regulator. When is applied 24 V Vtrans, capacitor is charged until 39 V at maximum then fault pin goes low without any under or over voltage (I ever saw in osciloscope). I observed there is no ground plane under LT3751 layout. This fact has anything to do with my issue? Thanks in advance.
