HSOIC (DDA)-8-29.4 mm² 4.9 x 6
The LMR33620 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 LMR33620 drives up to 2 A of load current from an input of up to 36 V. The LMR33620 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 LMR33620 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 LMR33620 is available in an 8-pin HSOIC package and in a 12-pin 3 mm × 2 mm next generation VQFN package with wettable flanks. This device is also available in an AEC-Q100-qualified version.
