LM5118
Overview
The LM5118 wide voltage range Buck-Boost switching regulator controller features all of the functions necessary to implement a highperformance, cost-efficient Buck-Boost regulator using a minimum of external components. The BuckBoost topology maintains output voltage regulation when the input voltage is either less than or greater than the output voltage, making it especially suitable for automotive applications.
