Low Noise Split Rail Non-Isolated Boost + - 12V Power Supply (LOWNOISESPLITRAILNONISO-BOOST-REF)

This circuit boosts 5V to a low noise +/- 12V bias at 40mA for use in analog circuitry. This design uses the LM5001 fully integrated switch mode regulator in concert with a very small EP5 transformer to create a non-isolated positive and negative power rail (for isolation see "В± 5V Isolated, Low Noise Split Rail Generator User Guide" below). This design uses less than 1 square inch of double sided PCB with components on only one side. The same basic circuit can be used to develop other voltages such as +/- 15V or +/- 5V.
