Description

General part information

LMR24210 Series

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 1 A to loads with an output voltage as low as 0.8 V. Dual N-channel synchronous MOSFET switches allow a low component count, thus reducing complexity and minimizing board size.

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 VCCunder-voltage lock-out, output overvoltage protection, thermal shutdown, and gate-drive undervoltage lockout. The LMR24210 is available in the small DSBGA low profile chip-scale package.
