Different control schemes PWM voltage and current mode control as well as hysteretic control are discussed in terms of load transient response. A hysteretic mode controller circuit will be shown and compared to a voltage mode PWM controller circuit. Measurement results from these circuits complement the paper. 
Different Methods of Control Mode in Switch Mode Power Supply- A Comparison
Switch mode power supplies are used in nearly all electronic devices in our day today life and in industries. Many control methods are developed for the control of DC-DC converter. To obtain a

The voltage-mode hysteretic converter is one of ripple-based regulators. The converter has the salient features of fast transient response, good conversion efficiency, and simple architecture.
A fast hysteretic buck converter with adaptive ripple controller
TLDR
The paper presents the design of a fast voltage-mode hysteretic buck converter with adaptive ripple controller, a circuit which automatically generates a virtual hysteresis window for the hySteretic comparator such that the output voltage ripples are stable within the fixed hysteResis window according to the load conditions.
