Introduction
The LM34923 EVAL 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 of 6V to 75V. The circuit delivers load currents to 500 mA, with current limit set at a
nominal 1 Amp.
