www.ti.com SNVS671E – FEBRUARY 2011 – REVISED MARCH 2013 12A High Efficiency Synchronous Point of Load Buck Regulator with Frequency
Synchronization
Check for Samples: LM21212-1 FEATURES DESCRIPTION The LM21212-1 is a monolithic synchronous point of
load buck regulator that is capable of delivering up to
12A 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. 1 2 Integrated 7.0 mΩ High Side and 4.3 mΩ Low
