When the measured current of the load after driving with 4.5V is 0.8A to 1.2A-2A, the voltage will be pulled down to 0.9V-1V and then restored. In the above figure, there is a CCAMP capacitor that has been changed to 4.7nF without improvement.
Could you please help check if the schematic diagram has problems?
How may i improve this phenomenon?
Thanks
