I was planning to use two TPS82150 devices to generate +/-5V from +/-15V, and have been looking for an application note to generate negative 5V from my negative 15V rail.
I have seen the example Inverting Power Supply Schematic in Figure 30, but this doesn't work for me as +15V to -5V exceeds maximum supply voltage, and it is preferred that I use the -15V rail.
I just wondered if I was missing a simple solution?
