3.8-V to 36-V, 3-A synchronous step-down voltage converter

The LMR33630-Q1 automotive-qualified regulator is

an easy-to-use, synchronous, step-down DC/DC converter that delivers best-in-class

efficiency for rugged applications. The LMR33630-Q1 drives up to 3 A of load

current from an input of up to 36 V. The LMR33630-Q1 provides high light load

efficiency and output accuracy in a very 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-Q1 automatically folds back frequency

at light load to improve efficiency. Integration eliminates most 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 LMR33630-Q1 is available in a 12-pin 3 mm × 2

mm next generation VQFN package with wettable flanks.
