Hello,
My converter needs parallel operation of two sepic converters. Below are the specification:
Vin for 3481: 15V
Vin for converter: 19V to 100V
Vout: 72V
As per design individuly they are working fine. But when I connect both the converters in parallel the problem starts. The current sharing is uneven (that is expected becuase of the component tolerance) but when the load increases one converter switch its pulses off.
My doubt is is there any way/suggestions for paralleling of LM3481, where I can get synchronized and parallel shared output current.
I am attacheing rough schematic for general idea .
Please help if anyone has any idea.
Thank you.
