The LMR336x0AP-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 LMR336x0AP-Q1 drives up

to 2 A or 3 A of load current from an input of up

to 36 V. The LMR336x0AP-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

LMR336x0AP-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 LMR336x0AP-Q1 is available

in a 12-pin 3-mm × 2-mm next generation VQFN

package with wettable flanks.

•

High power conversion at all loads

– Peak efficiency > 95%

– Low shutdown quiescent current of 5 µA

– Low operating quiescent current of 25 µA
