Keywords:Industrial control equipment? programmable logic controllers? sensors? amplifiers? multiplexers?

Industrial control equipment such as programmable logic controllers, I/O modules, mass flow controllers, and various other sensors and supporting systems use analogue components like amplifiers and multiplexers that operate on negative supply voltage. Typically operating at 12V, 18V or other variations, these voltages are generated from a 24V DC bus. Maxim's portfolio of high-voltage synchronous buck regulators offer 50% lower power loss allowing customers to operate their equipment 50% cooler. In this application note, we discuss techniques to use these synchronous buck regulators to generate negative voltages.
