DESCRIPTION  
The LM21215 is a monolithic synchronous point of  
load buck regulator that is capable of delivering up to  
15A of continuous output current while producing an  
output voltage down to 0.6V with outstanding  
efficiency. The device is optimized to work over an  
input voltage range of 2.95V to 5.5V, making it suited  
for a wide variety of low voltage systems. The voltage  
mode control loop provides high noise immunity,  
narrow duty cycle capability and can be compensated  
to be stable with any type of output capacitance,  
providing maximum flexibility and ease of use.
