The 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 drives up
to 3 A of load current from an input of up to 36 V. The LMR33630 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 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 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.
