Abstract
Analog pulse width modulation (PWM) control circuits and techniques are presented for improving output voltage load transient response in controlling DC to DC conversion systems in which a transient detector circuit restarts a PWM carrier ramp waveform to initiate asynchronous injection of a pulse between the regular periodic PWM pulses in a fixed frequency pulse stream to mitigate the effect of output inductor energy depletion on output voltage.
