LM25576EVAL Datasheet PDF - TI

●The LM25576EVAL is an evaluation board designed to provide the design engineer with a fully functional power converter based on emulated current mode control to evaluate the LM25576 regulator IC. The LM25576 is an easy to use SIMPLE SWITCHER buck regulator which allows design engineers to design and optimize a robust power supply using a minimum set of components. The regulator utilizes an emulated current mode architecture which provides inherent line regulation, tight load transient response, and ease of loop compensation without the usual limitation of low duty cycles associated with current mode regulators. The evaluation board provides a 5V output with a 3A current capability. The design operates at 300KHz, a good compromise between conversion efficiency and solution size. The printed circuit board consists of two layers of two ounce copper on FR4 material with a thickness of 0.06inches.
