LM5118EVAL/NOPB Datasheet PDF - TI

The LM5118EVAL/NOPB evaluation board is designed to provide the design engineer with a fully functional, emulated current mode control, buck boost power converter to evaluate the LM5118 controller IC. The evaluation board provides a 12V output with 3A of output current capability. The evaluation board operates at 300kHz, a good compromise between conversion efficiency, tradeoffs between buck and buck boost mode requirements and converter size. The printed circuit board consists of four layers with two ounce copper top and bottomland one ounce copper on internal layers. The board is constructed with FR4 material.
