LMR24210 Small Footprint 42V Buck Regulator 1A Evaluation Board


Order now


The LMR24210/20 Step Down Switching Regulator features all required functions to implement a cost effective, efficient buck power converter capable of supplying up to 1.0A or 2.0A. The Constant On-Time (COT) regulation scheme requires no loop compensation, results in a fast load transient response and simple circuit implementation, this allows low component count, and consequently very small overall board space. The regulator can function properly even with an all ceramic output capacitor network, and does not rely on the output capacitor`s ESR for stability. The LMR24210/20 has a wide input range from 4.5V-42V, making it suitable for a variety of applications from automotive to power conditioning of unregulated sources. The LMR24210/20 Evaluation Board is designed to provide the design engineer with a fully functional power converter to evaluate the LMR24210/20 series of buck regulators.
