IC LM2585 is switch regulator and it change 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.
When switch is OFF energy from L1 add extra voltage to input.
Diode D1 send energy to output capacitor C1.
C1 keep output steady at 15V and C4 help input voltage.
R1 and R2 feedback control switch ON/OFF to keep 15V output.
C2, C3 and C4 filter keep circuit stable and reduce voltage changes and make system smooth.
