The LM25118 Evaluation Board is designed to provide the design engineer with a fully functional, Emulated Current Mode Control, buck boost power converter to evaluate the LM25118 controller IC. The evaluation board provides a 12V output with 3A of output current capability. The evaluation board’s wide input voltage range is from 42V to 5V, with operation down to 3V with some component changes. The evaluation board operates at 300 kHz, a good compromise between conversion efficiency, tradeoffs between buck and buck-boost mode requirements, and converter size. The printed circuit board consists of 4 layers with 2 ounce copper top and bottom, and 1 ounce copper on internal layers. The board is constructed with FR4 material.
