60V input dc/dc controller said to simplify design

The LTC3863 from Linear Technology is a high voltage inverting dc/dc controller that uses only one single inductor to produce a negative voltage from a positive input voltage.

While most low to medium power inverters utilise a coupled inductor topology, or transformer, all of the LTC3863's interface signals are positive ground referenced, which Linear says simplifies the design process. In addition, none of the device's pins are connected to a negative voltage, which allows the output voltage to be limited only by the selection of external components. The LTC3863 has a low 70µA quiescent current in standby mode to help increase the run time in battery powered applications. Its output voltage can be set from -0.4 to -150V or lower at up to 3A typical; making it suitable for 12 or 24V automotive, heavy equipment, industrial control, robotic and telecom applications.
