l9110 driver to drive Nema17 stepper

i have laser engraver board uses l9110 driver ic drive cd rom motors want use on new project uses nema 17 stepper motors.

my quest how boost output of 800ma upto 2000ma required nema 17,

any ideas suggestion highly appreciated

don't.

you want use higher voltage higher current.

get suitable stepper motor driver - a  pololu drv8825 may suitable about. higher current driver better if motor requires 2 amps.

post link datasheet motor. nema 17 describes size of front face.

see stepper motor basics.
