Controlling Output Ripple & Achiev ESR Indep Constant On-Time Reg Designs (Rev. A)
PDF, 178 Kb, Revision: A, File published: Apr 23, 2013
Of all the voltage regulator control strategies ever devised, the hysteretic regulator is probably about thesimplest. This control methodology simply turns a switch on when the output voltage is below a referenceand turns the switch off when the output rises to a slightly higher reference. The output ripple is thereforea direct function of the difference between the upper and lower reference
