SNOSB87C – MARCH 2011 – REVISED JANUARY 2016 LM21215A 15-A Ultra High-Efficiency Synchronous Buck Converter With Frequency
Synchronization
1 Features 3 Description The LM21215A is a synchronous buck DC-DC
converter that delivers up to 15 A of output current at
output voltages as low as 0.6 V. Operating over an
input voltage range of 2.95 V to 5.5 V with ultra-high
efficiency, the LM21215A suits a wide variety of low
voltage systems. The voltage-mode control loop with
high gain-bandwidth error amplifier provides high
noise immunity, narrow duty cycle capability and is
easily compensated for stable operation with any type
of output capacitor, providing maximum flexibility and
ease of use. 1 High-Efficiency Synchronous DC-DC Converter
