DescriptionThe LMR33620-Q1 automotive-qualified regulator is an easy-to-use,synchronous, step-down DC/DC converter that delivers best-in-class efficiency for ruggedapplications.The LMR33620-Q1 drives up to2A of load current from an input of upto 36 V. The LMR33620-Q1provides high light load efficiency and output accuracy in a very small solution size. Featuressuch as a power-good flag and precision enable provide both flexible and easy-to-use solutions fora wide range of applications. The LMR33620-Q1 automatically folds back frequency at light load to improveefficiency. Integration eliminates most external components and provides a pinout designed forsimple PCB layout. Protection features include thermal shutdown, input undervoltage lockout,cycle-by-cycle current limit, and hiccup short-circuit protection. The LMR33620-Q1 is availablein a 12-pin 3 mm × 2 mm VQFN package with wettable flanks.
