"(38 amp to 110 amp)"
I hope you don't believe this; me NOT.
Make difference between A and mA!!!
Please, post accurate information.
Enable signal on R7551 pins, has different names; check schematic
"Pin 1 on R7551 P5VS4RS3_EN Present
Pin 2 on R7551 P5VS4RS3_EN fluctuates"
What we should understand from this???
"Fluctuating how?
Do you get pulse every 2, or 5 seconds?
Or the voltage fluctuates continuosly?"
Can we get a clear answer?
L7560 = 3.3 V
L7520 = 5V
L7630 = 1.05
L7430 = 2V (Pin 2 end of the coil is disconnected from the board)... This should be 1.2V, but I am getting 2V on Pin2 of the coil which is disconnected from the board. ANY Solutions?
Board looks clean to me ....I am checking under microscope
is it possible ? L7430 = 2V (Pin 2 end of the coil is disconnected from the board)... This should be 1.2V, but I am getting 2V on Pin2 of the coil which is disconnected from the board
