Synchronous rectification keeps efficiency high at the large step-down ratios this part handles — a 5V-to-1.2V conversion at 12A loses less heat in the low-side FET than a diode-based design would. ## Switching frequency and thermal — layout decisions The 300 kHz to 1.55 MHz switching range lets you trade inductor size against switching loss. At the high end the inductor shrinks to a 1 µH class footprint, but the FET switching losses and core losses climb.","metaTitle":"Texas Instruments LM21212MH-2/NOPB Buck Regulator, 12A","metaDescription":"Active-production 12A step-down buck regulator from TI. 2.95-5.5V input, adjustable output down to 0.6V, 20-HTSSOP package.
