LM5574EVAL

TEXAS INSTRUMENTS  LM5574EVAL  评估板, 降压转换器, SIMPLE系列, 75V, 0.5A

The evaluation board is designed to provide the design engineer with a fully functional power converter based on emulated current mode control to evaluate the LM5574 regulator IC. The evaluation board provides a 5V output with a 0.5A current capability. The ultra wide input voltage ranges from 7V to 75V. 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 0.06 inches.
