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 LTC3896вЂ™s ability to handle
high input voltages eliminates the need for bulky and
costly voltage suppressors, while the low minimum …
