I'm looking for an Inverting Buck-Boost power supply with input of 8 - 10V, output -9V at 10 mA to 100mA.
In my application I'm concerned about noise. I'm planning to sync the power supply to one of my clocks. A converter that pulse skips 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 light loads. I don't care too much about efficiency, but I don't want to have a big dummy load. Also note that the sync signal will not be available until some time after startup.
Can someone at TI suggest a converter that would meet these requirements?
