♠ LM63635-Q1 3.5-V to 36-V, 3.25-A, Automotive Step-down Voltage Converter
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 3.25-A of load current from an input of up to 36 V for WSON package and 32 V for HTSSOP package. 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 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 shortcircuit protection. The LM63635-Q1 is available in both the HTSSOP 16-pin power package, with PowerPAD™, and the WSON 12-pin power package.
