Description for the LMR24220

The LMR24220 synchronously rectified buck converter features all required functions toimplement a highly efficient and cost effective buck regulator. It is capable of supplying 2-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 LMR24220 does not rely on output capacitorESR for stability. The device is designed to work exceptionally well with ceramic and other verylow ESR output capacitors. It requires no loop compensation, results in a fast load-transientresponse and simple circuit implementation. The operating frequency remains nearly constant withline variations due to the inverse relationship between the input voltage and the on-time. Theoperating frequency can be externally programmed up to 1 MHz. Protection features includeVCC undervoltage lockout, output overvoltage protection, thermal shutdown,and gate drive undervoltage lockout. The LMR24220 is available in the small DSBGA low profilechip-scale package.
