The LT8709 is unique in solving the problem of regulating a negative voltage with respect to system ground, without the need of complicated level shifting circuitry. As such, the LT8709 is a negative input synchronous multi-topology DC/DC controller that can be used for negative-to-negative or negative-to-positive DC/DC power conversion. It can be easily configured in buck, boost, buck-boost, and inverting topologies.
