... LM25007 Evaluation Board Introduction The LM25007EVAL evaluation board provides the design engineer with a fully functional buck regulator, employing the constant on-time (COT) operating principle. This evaluation board provides a 5V output over an input range 42V. The circuit delivers load currents to 450 mA, with current limit at )670 mA ...
