Other Parts Discussed in Thread: TPS53355
Hi,
I'm working on a design that uses the lm3150 to generate 1.0V 12A (from 12V) for the core of a CPU. This works fine, however the CPU has a voltage scaling control that is connected to the FB pin of the device through a resistor. I am told (by the CPU vendor) that this should work once the unity gain bandwidth of the DC/DC is in the range 15-300kHz. I can't find this info for this device - can you help?
I am finding the 1.0V is scaling up to 1.6V, which it shouldn't so I'm trying to debug and it's obviously to do with the feedback control from the CPU - can you help with the query above?
