Battery powered systems or systems with low input voltage supplies may have loads that require higher voltage outputs. A boost converter is a usual choice for non-isolated applications; however, boost converters do not naturally provide system protection to downstream circuitry due to the pass path from input to output. Problems due to this pass path are now resolved with the LM5121 boost controll
