When ratio of pulse width to pulse spacing exceeds value set by R12, width of output pulse is automatically reduced to maintain duty cycle at preset maximum. Used as pulse driver for high-power amplifier when duty cycle must be limited to prevent overheating. If duty cycle is set for 50% and frequency is increased, output will be square wave for all frequencies up to maximum frequency limit for circuit. R9 adjusts output pulse width from 0.7 to 7 microsec.-D. N. Lee, Monostable Multi With Adjustable Duty Cycle, EEE, 13:9, p 92-94.
