نظرة عامة على المنتج
The LMR10510XMF/NOPB from Texas Instruments is a 1MHz step-down (buck) DC-DC converter in a tiny SOT-23-5 package. It features a fixed 1.8V output (X suffix), 1A output current, 2.7V to 5.5V input range, and greater than 90% efficiency with internal compensation, making it ideal for point-of-load regulation in space-constrained applications.
