TPS65279 Overview
TPS65279 is a monolithic dual synchronous buck converter with wide 4.5-V to 18-V operating input voltage range that enpassed most intermediate bus voltage operating off 5-, 9-, 12- or 15-V power bus or battery. The converter with constant frequency peak current mode control is designed to simplify its application while giving the designers options to optimize their usage according to the target applications.
