The LM5118MHX is a wide input voltage range buck/boost switching regulator controller that provides all the features required to achieve high performance and cost-effective buck/boost regulators with minimal external components. The buck/boost topology maintains a stable output voltage when the input voltage is lower or higher than the output voltage, making this device ideal for automotive applications. When the input voltage is sufficiently greater than the regulated output voltage, the LM5118MHX operates as a buck regulator, then gradually transitions to the corresponding buck/boost mode as the input voltage approaches the output voltage. This dual-mode approach maintains regulation over a wide input voltage range, provides optimal conversion efficiency in buck mode, and ensures interference-free output during mode transitions. The controller is easy to use and includes drivers for both high-side buck MOSFETs and low-side boost MOSFETs. This regulator control method is based on current-mode control using simulated current slopes. Simulated current-mode control reduces the noise sensitivity of the pulse-width modulation circuit, enabling reliable control of extremely low duty cycles required in high-input-voltage applications. Additional protection features include current limiting, thermal shutdown, and enable input. The LM5118MHX is available in a power-enhanced 20-pin HTSSOP package with exposed chip connection pads for improved thermal performance.
