The components are inexpensive, consisting of a P-MOSFET (for use in the positive rail) with a dual PNP transistor and two resistors. Q1 and Q2 form a current mirror circuit that act as a differential amplifier which responds to the voltage drop across the MOSFET.
Here's the first of two simple PWM control circuit using inexpensive readily-available components. The circuit component values shown are for a 12V supply but could be altered for other supply voltages less than 15V. Most of the work is done by...
