Texas Instruments' LMR33630 SIMPLE SWITCHER regulator is an easy-to-use, synchronous, step-down DC/DC converter that delivers best-in-class efficiency for rugged industrial applications. The LMR33630 can drive up to 3 A of load current from an input of up to 36 V. The device provides high light-load efficiency and output accuracy in an ultra-small solution size. Features such as a power-good flag and precision enable provide both flexible and easy-to-use solutions for a wide range of applications. The LMR33630 automatically folds back frequency at light-load to improve efficiency. Integration eliminates most external components and provides a pin-out designed for a simple PCB layout. Protection features include thermal shutdown, input under-voltage lockout, cycle-by-cycle current limit, and hiccup short-circuit protection. The converter is available in an 8-pin HSOIC package and in a 12-pin, 3 mm × 2 mm VQFN package with wettable flanks. This device is available in an AEC-Q100 qualified version.
