Bench power supply circuit using LTC3600 buck regulator

This bench power supply circuit is designed using LTC3600 buck regulator. This bench power supply circuit using LTC3600 buck regulator is capable to provide a maximum output current up to 1.5A . Output voltage of this lab power supply can be varied from 0 to 12 volts .
Output voltage can be external programmed from 0V to 0.5V below VIN using just one
external resistor .
The operating supply voltage range of the LTC3600 circuit is 4V to 15V, but for this power supply electronic project is required a 15V input.
