DESCRIPTION  
The LMR24210 Synchronously Rectified Buck  
Converter features all required functions to implement  
a highly efficient and cost effective buck regulator. It  
is capable of supplying 1A to loads with an output  
voltage as low as 0.8V. Dual N-Channel synchronous  
MOSFET switches allow a low component count, thus  
reducing complexity and minimizing board size.  
No Loop Compensation Required  
COT Architecture with ERM  
28-Bump DSBGA (2.45 x 3.64 x 0.60 mm)  
Packaging  
Fully Enabled for WEBENCH® Power Designer  
•
Different from most other COT regulators, the  
LMR24210 does not rely on output capacitor ESR for  
stability, and is designed to work exceptionally well  
with ceramic and other very low ESR output  
capacitors. It requires no loop compensation, results  
in a fast load transient response and simple circuit  
implementation. The operating frequency remains  
nearly constant with line variations due to the inverse  
relationship between the input voltage and the on-  
time. The operating frequency can be externally  
programmed up to 1 MHz. Protection features include  
VCC under-voltage lock-out, output over-voltage  
protection, thermal shutdown, and gate drive under-  
voltage lock-out. The LMR24210 is available in the  
small DSBGA low profile chip-scale package.  
PERFORMANCE BENEFITS  
•
•
Tiny Overall Solution Reduces System Cost  
Integrated Synchronous MOSFETs Provides  
High Efficiency at Low Output Voltages  
•
•
COT with ERM Architecture Requires No Loop  
Compensation, Reduces Component Count,  
and Provides Ultra Fast Transient Response  
Stable with Low ESR Capacitors
