3.5-V to 36-V, 2.5-A step-down voltage converter with spread spectrum

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 designs 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 packageand the WSON 12-pin power package.
