In my application, I want to generate -9V/50mA from 12V Input. What are options available?
I have come across few options as below:
Buck regulator to generate -ve output by changing OUTPUT and GND pins. For such low load current, possibility is that it will operate in DCM mode.
2) Dual Pump Charge Output http://www.farnell.com/datasheets/9917.pdf
I need IC which will take and generate -9V.
