  Starting Up A Buck Regulator With a Voltage Present At V OUT (Rev. A)
  PDF, 31 Kb, 修订版: A, 档案已发布: Apr 30, 2013
  This application report describes a buck regulator’s inability to startup when there is a voltage alreadypresent at the regulator’s output (VOUT). Although the LM5007 is used in this application report, the samediscussion applies to the LM50xx and LM349xx series of buck regulators.

  Controlling Output Ripple & Achiev ESR Indep Constant On-Time Reg Designs (Rev. A)
  PDF, 178 Kb, 修订版: A, 档案已发布: 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
