... LM25010 Evaluation Board Introduction The LM25010EVAL 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 1A, with current limit set at )1 ...
