1-inductor, 60-V input, low IQ inverting DC/DC controller

摘要

Linear Technology Corporation's LTC3863 is a high voltage inverting DC/DC controller that uses just a single inductor to produce a negative voltage from a positive input voltage. Most low to medium power inverters utilize a coupled inductor topology, or transformer which increases the circuit size and complexity. The LTC3863 simplifies the design further with all of its interface signals being positive ground referenced. None of the LTC3863 pins are connected to a negative voltage allowing the output voltage to be limited only by the selection of external components.
