The LM34930 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 8V to 33V. The circuit delivers load currents to 1A, with current limit set at the nominal 1.16A. The board is populated with all components except R5, C9 and C10. These components provide options for managing the output ripple.
