LM21212-1 Overview
The LM21212-1 is a monolithic synchronous point-ofload buck regulator that is capable of delivering up to 12 A of continuous output current while producing an output voltage down to 0.6 V with outstanding efficiency. The device is optimized to work over an input voltage range of 2.95 V to 5.5 V, making it suited for a wide variety of low voltage systems. The voltage mode control loop provides high noise immunity,...
