Hysteretic Buck Regulators
Objective:
Upon completion of this course the student will be
able to:
Explain the differences between a Hysteretic Buck Regulator
and a PWM Regulator.
Given the appropriate component values, calculate the
switching frequency of a Hysteretic Buck Regulator circuit.
List two advantages of a Hysteretic Buck Regulator over a
PWM Regulator.
Explain what circuit modifications could be made to enable
the use of low ESR (Equivalent Series Resistance) output
capacitors.
Description: Simple voltage mode and current
mode hysteretic buck regulators. No compensation needed. How
regulation is achieved. Error in the Vout. Delay in the
system. How frequency is determined. Ceramic Cout in voltage
mode. Real examples.
