I am setting to work a digital interface board that has some legacy analogue circuitry requiring +/-15v, 200mA supply. The board is powered by +5V. Using a TPS65131, which gives -15V with no problem, however the +15V is at 4.7V and there is no switching output. The resistor divider for the positive side is 1.8M and 158K and the enable line is at 5V. Any ideas on why it is not working. I do not use the BSW output to switch off the +5V supply.
