i want to make dual supply output with single supply input. So how to get 39 V dual supply of ADP5070 EVM with 12 V input.
The switching transistors in the ADP5070 are rated to 39 V. This means on the negative supply, with a 12 V input, the maximum output will be -27 V. The positive output of +39V is ok. I would suggest the ADIsimPower design tools are used to setup the compensation for alternative voltages - they can be downloaded here: http://download.analog.com/PMP/ADP507x_Designer.zip Alternatively the datasheet has a number of tested configurations for common output voltages listed in the tables towards the end of the document
