ABSTRACT:
A solid state electronic motor power control circuit for portable paint pumps having a MOSFET power control device and an operational amplifier connected to the MOSFET to selectively operate as a switch driver in a first state and as a linear gain amplifier in a second state. The operational amplifier has a feedback path from the motor to compensate for motor load variations.
