Other Parts Discussed in Thread: LM5117
I have an implementation using LM25117 running continuous conduction mode with Vout = 3.3V
With a load of 2A, the Current Monitor output is practically at zero level.
With a load of 2.86A, the Current Monitor output generates a burst of pulses - see first image below
With a load of 3.66A, the Current Monitor output generates a DC level with a high amplitude AC component riding on top - see second image further below
[1] What is the reason for CM not to produce an output voltage proportional to the 2A load?
[2] Is there a condition where CM is not enabled (by design or by operation)
[3] Is the operation of CM dependent on the component selection of any other subsystems?
[4] What other components can be checked to verify the operation of the CM sub-circuit?
Regards,
Oscar.
