In my application I'm concerned about noise. I'm planning on syncing the power supply to one of my clocks. If the converter utilizes pulse skipping, that may move the noise spectrum down into my frequency band of interest, so I'd like a design that doesn't pulse skip even at low loads. I don't care too much about efficiency, but I don't want to have a big dummy load. Can you suggest a synchronous converter that would stay in CCM with no pulse skipping? My requirements are not that complicated: input 8-10V, output -9V at 10mA to 100mA, need to sync to external clock and maintain low noise. What TI chip would you suggest?
