Rm28525 Schematic Diagram Updated Work

: Use a Multimeter to verify the control signal reaches terminals 3 and 4 before assuming the component has failed.

Programming and test

Look for a series RC network between the output of the error amplifier and ground. The updated diagram uses exact values (C206 = 470pF, R208 = 4.7kΩ). Substituting these with generic values causes oscillation. rm28525 schematic diagram updated
