LTC3869 12 volt and 5 volt high current power supply

Using the LTC3869 high performance dual synchronous step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages can be designed a very simple and efficiency high current power supply circuit that will provide 12 and 5 volt output voltage . This LTC3869 dual output power supply electronic project accepts a high range input voltage between 13 and 38 volts . A constant frequency current mode architecture allows a phase-lockable frequency of up to 780kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out-of-phase.

This power supply circuit project has a switching frequency of 250kHz and will provide a maximum output current of 6 ampere for 12 volts output and 10 ampere maximum output current for the 5 volts output .
