Using the LTM4613 switching regulator circuit designed by Linear Technology can be designed a very simple power supply electronic project that will provide a 12 volt output voltage at a maximum output current of 8 ampere .This LTM4613 switching regulator circuit ha included in the package are the switching controller, power FETs, inductor and all support components. This switching power supply require an input voltage range between 22 and 36 volt .
The onboard input filter and noise cancellation circuits achieve low noise coupling, thus effectively reducing the electromagnetic interference . In a typical 8A output application, three very low ESR, X5R or X7R, 10μF ceramic capacitors are recommended for C1-C3.
The LTM4613 has an integrated constant on-time current mode regulator, ultralow RDS(ON) FETs with fast switching speed and integrated Schottky diodes.
The typical switching frequency is 600kHz at full load at 12V output.
