Using the LTC3600 lab power supply 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 .
A simple lab power supply electronic project can be designed using this circuit diagram which is based on the LM2576 monolithic integrated regulator that provide all the active functions for a step-down (buck) switching regulator .
This simple lab power supply circuit diagram is designed to provide an variable output voltage between 1.2 to 35 volts at a maximum current of 3A .
A very lab adjustable power supply that can provide an output voltage between 0 and 60 volts can be designed using this circuit diagram . This lab power supply can be designed with LM723 chip or for higher output voltages, with L146 .
