0-30V voltage and 0-3 to the current set-switched ( switching dc-dc ) digital power supply project control floor ATMEGA644 microcontroller used system designed as a dual ATMEGA644 2 power voltage Check the floor, viewing on current information LCD screens. The LT1074 5-amp step-down dc-dc regulator integrates the LT1084 5-ampered dc-dc regulator integration after the power supply is switched on. The LT6105 current sensing integrated on the 0.02 ohm resistor is connected to the output of the voltage divider resistors and voltage adjustments are made by the control stage.
Toroidal transformer used as voltage source 230 V primary input secondary outputs 32 V AC 3.2 A 7 V AC 0.1 A 7V AC 0.3 A.
0.3 A 0.30 V Adjusted Lab power supply source eagle cad pcb schematic drawings and ATMEGA644 code files are available.
