Texas Instruments LM34919CQSDEVM
The LM34919CQSDEVM 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 3.3V output over an input range of 4.5V to 50V. The circuit delivers load currents to 600 mA, with valley current limit set at 640mA.
