Hi,
I am working on a design using a BQ24773 to charge a pack of Li-Ion batteries. I am now in the age-old predicament where we are having troubles getting the design through its CE marking, based on its radiated emissions.
I appreciate that this is an ambiguous question to ask, especially without being able to show the schematics/layout, but I thought I would reach out to the community here and see if this problem has occurred before.
I have tried all the obvious tricks with this, such as optimising the layout, choosing low ESR capacitors, increasing gate resistors to reduce ringing etc. Regardless of this, any help or tips would be greatly appreciated if anyone has had the same experience with this device.
Many thanks
Chase
