I'm looking for a switching regulator chip (buck-boost, sepic, or other topology) to convert 2~7V input to 5V. I realize it's easier to have an input voltage range that's consistently higher or lower than the output, but this is what I need. It also needs to support 10W output (2A@5V), and I'm looking for a relatively low-cost solution with minimal external component count. Any suggestions?
