The LM25085 evaluation board provides the design engineer with a fully functional buck regulator, employing the LM25085 PFET switching controller which uses the constant on-time (COT) operating principle. The evaluation board provides a 5V output over an input range of 5.5V to 42V. The circuit delivers load currents to 5A, with current limit set at ≅8.2A. The board is populated with all components except C5.
