Hi,
Input: 6-24V, output VDR=12V, maximum load current 0.3A. C17 has been changed to 270PF, and other parameters are shown in the schematic diagram.
Problem phenomenon: Sometimes it cannot be started, and when touching peripheral devices with your hand or pen, it can be started again.
In addition, the inductance is 47UH, 1.75A. If circuit parameters need to be modified, try to modify the peripheral resistance and capacitance devices without changing this inductance.
