The LMR24210TLX/NOPB synchronously rectified buck converter features all required functions toimplement a highly efficient and cost effective buck regulator. It is capable of supplying 1 A toloads with an output voltage as low as 0.8 V. Dual N-channel synchronous MOSFET switches allow alow component count, thus reducing complexity and minimizing board size.
Different from most other COT regulators, the LMR24210TLX/NOPB does not rely on output capacitorESR for stability, and is designed to work exceptionally well with ceramic and other very low ESRoutput capacitors. It requires no loop compensation, results in a fast load transient response andsimple circuit implementation. The operating frequency remains nearly constant with line variationsdue to the inverse relationship between the input voltage and the on-time. The operating frequencycan be externally programmed up to 1 MHz. Protection features include VCCunder-voltage lock-out, output overvoltage protection, thermal shutdown, and gate-driveundervoltage lockout. The LMR24210TLX/NOPB is available in the small DSBGA low profile chip-scale package.
