LM105 positive regulator serves as amplifier-reference for LM195 power transistor IC in switching regulator. Duty cycle of switching action adjusts automatically to give constant output. Q2 consists of four LM195s in parallel since each is rated at only about 2 A. R8 serves as output voltage control- Linear Applications, Vol. 2, National Semiconductor, Santa Clara, CA, 1976, AN-110, 3.9V p4.
