The LM636x5-Q1 is an easy-to-use, synchronous, step-down DC/DC converter designed for rugged automotive applications. The LM636x5-Q1 can drive up to 1.5A or 2.5A of load current from an input of up to 36V. The converter has high light load efficiency and output accuracy in a small design size. Features such as a RESET flag and precision enable provide both flexible and easy-to-use solutions for a wide range of applications. Automatic frequency foldback at light load improves efficiency while maintaining tight load regulation. Integration eliminates many external components and provides a pinout designed for simple PCB layout. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limit, and hiccup short-circuit protection. The LM636x5-Q1 is available in the HTSSOP 16-pin power package, with PowerPAD™ integrated circuit package, and the WSON 12-pin power package.
