  U-156 The UC3886 PWM Controller Uses Average Current Mode Control
  PDF, 794 Kb, Datei veröffentlicht: Sep 5, 1999
  The continuing development of high-performance processors is imposing stringent requirements on their respective power systems. Intel's Pentium(r)Pro power system specification, for instance, demonstrates the industry trend to operate at lower voltages and at higher currents, with tight regulation and fast transient response. The UC3886 Average Current Mode PWM Controller meets these requirements.

  U-157 Fueling the Megaprocessor - A DC/DC Converter Design
  PDF, 678 Kb, Datei veröffentlicht: Sep 5, 1999
  This application note provides a detailed account of design tradeoffs and procedures for the development of a voltage regulator module (VRM) for the Intel Pentium (r)Pro processor. This voltage regulator features Unitrode's UC3886 Average Current Mode PWM Controller and UC3910 4-BIT DAC and Voltage Monitor ICs configured in a buck regulator. Test results and waveforms show how the VRM power supply

  Basic Calculation of a Boost Converter's Power Stage (Rev. C)
  PDF, 186 Kb, Revision: C, Datei veröffentlicht: Jan 8, 2014
  This application note gives the equations to calculate the power stage of a boost converter built with an IC with integrated switch and operating in continuous conduction mode. It is not intended to give details on the functionality of a boost converter (see Reference 1) or how to compensate a converter. See the references at the end of this document if more detail is needed.
