HTSSOP (PWP)-16-32 mm² 5 x 6.4
The LM63635-Q1 regulator is an easy-to-use, synchronous, step-down DC/DC converter designed for rugged automotive applications. The LM63635-Q1 can drive up to 3.25A of load current from an input of up to 36V for WSON package and 32V for HTSSOP package. 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 LM63635-Q1 is available in both the HTSSOP 16-pin power package, with PowerPAD™ integrated circuit package, and the WSON 12-pin power package.
