LM63635D-Q1 Step-Down Voltage Converters

Texas Instruments LM63635D-Q1 Step-Down Voltage Converters are easy-to-use, synchronous, step-down DC/DC converters designed for rugged automotive applications. The LM63635D-Q1 can drive up to 3.25A of load current from an input of up to 32V. The converter has high light-load efficiency and output accuracy in a small solution size. Features such as a RESET flag and precision enable provide both flexible and easy-to-use solutions for various 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 a simple PCB layout. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limit, and hiccup short-circuit protection. The LM63635D-Q1 is available in the HTSSOP 16-pin power package with PowerPAD™. The Texas Instruments LM63635D-Q1 devices are AEC-Q100 qualified for automotive applications.
