App note: Generating negative output voltage from positive input voltage using MAX17291 boost converter IC with active discharge feature

App note from Maxim Integrated about their MAX17291 generating negative voltage from positive input. Link here

Many applications require the power supply to provide a negative voltage, such as LCD displays, gate drivers, embedded applications, op-amp circuits, etc,. This application note explains how to generate a negative output voltage from a positive input voltage using the MAX17291 boost converter IC.
The MAX17291 is a low quiescent current boost (step-up) DC-DC converter with a 1A peak inductor current limit and True Shutdown™. True Shutdown disconnects the output from the input with no forward or reverse current. The output voltage is set with an external resistor-divider. The MAX17291 IC can operate from 1.8V to 5.5V input supply and can output up to 20V.
