LMR14050SDDA General Description

The LMR14050SDDA is a step-down voltage regulator manufactured by Texas Instruments. It is a highly efficient device that can step down an input voltage ranging from 4.5V to 42V to a programmable output voltage as low as 0.8V. The regulator can deliver a maximum output current of 5A with a peak efficiency of 95%. The LMR14050SDDA is equipped with an adjustable soft-start feature that allows for gradual ramp-up of the output voltage, minimizing inrush current. It also offers thermal shutdown and overcurrent protection to ensure safe operation under various conditions. The regulator comes in a small 8-pin WSON package, making it ideal for compact and space-constrained applications.

I order the fourth time, the boards are cool all subwoofers and radio recorders have changed blunted, thank you to the seller i recommend.

v**n 01/20/2023

good working. The distance detected is under 2 cmSo it is not the spec that is specified in the description

J**b 01/01/2022

Optocouplers came, packed in plastic antistatic blister. They look good. The main thing is not to original was. In the near future i will test and complement the review. In the parcel, the seller put a capacitor for 0.68 uf 400 v as a gift.
