  High Voltage, High Efficiency Positive to Negative
  Converter
  Design Note 561
  Victor Khasiev
  Introduction
  Positive to negative conversion (inverting output) is
  widely used in LCD devices, OLED displays, audio
  amplifiers, industrial machinery, semiconductor
  manufacturing process control equipment, measurement tools, testing systems, LED drivers and battery
  chargers. Many of these applications require high
  power levels and extended input voltage ranges, two
  inherent features of the LTC3896 positive to negative
  controller. This controller is especially well suited for
  automotive applications due to its ability to handle
  very high input and output voltages (total voltage
  stress can reach 150V), its ability to drive standard
  level MOSFETs and its low operating quiescent current 40ВµA (10ВµA in shutdown). Wide 7V to 72V Input to -12V at 5A Output
  Figure 1 shows a positive to negative converter
  based on the LTC3896. This solution delivers -12V
  at 5A from a 7V to 72V input voltage range. In the
  automotive market, the LTC3896’s ability to handle
  high input voltages eliminates the need for bulky and
  costly voltage suppressors, while the low minimum …
