To begin with, IC LM2585 is switch regulator and it changes 6V input to 15V output.
When LM2585 switch is ON and current flow in inductor L1 and then this L1 store energy in magnetic field and when switch is OFF energy from L1 add extra voltage to input.
Then diode D1 send energy to output capacitor C1 and then this C1 keep output steady at 15V and C4 help input voltage.
After that, R1 and R2 feedback control switch ON/OFF to keep 15V output and then C2, C3 and C4 filter keep circuit stable and reduce voltage changes and make system smooth.
How to Build:
To build a Step-Up Converter Circuit: 6V to 15V Boost Regulator follow the below mentioned steps:
- First, gather all the parts as per circuit diagram
- Next, connect IC1 LM2585 pin 1 to GND through resistor R3 and capacitor C2.
- After that, connect IC1 pin 2 between resistors R1 and R2.
- Then connect IC1 pin 3 to GND.
- Also, connect IC1 pin 4 to junction of pin 5 and inductor L1 coil and then connect IC1 pin 5 to junction of 6V input and inductor L1 coil.
- Now connect diode D1 between one terminal of L1 and one terminal of resistor R1.
- Further, connect capacitor C1 positive to 15V output and negative to GND.
- Finally, connect capacitor C3 between IC1 pin 5 and GND and then connect capacitor C4 positive to 6V input and negative to GND.
