  Conditioning a Switch-mode Power Supply Current Signal Using TI Op Amps
  PDF, 61 Kb, File published: Mar 23, 2000
  The switch-mode power supply primary current is often sensed using a power resistor. Using an op amp to amplify the current-sense signal can reduce cost and improve noise performance and efficiency. This report reviews the advantages of using an op amp circuit and analyzes the design criteria needed to choose the proper op amp.

  UCC38C42 Family of High-Speed BiCMOS Current-Mode PWM Controllers
  PDF, 280 Kb, File published: Feb 7, 2002
  Since their introduction in the mid 1980?s the bipolar UC3842 family of Pulse width modulation (PWM)controllers has grown to become the most widely-used control strategy in the power supply industry. [1] The reasons for success are quite clear the devices feature an elegantly simple yet very effective control architecture they use only 8 pins they can drive MOSFET gates directly and they offer

  DN-56A, Single Switch Flyback Circuit Converts + 5 V to +/- 12 V for RS-232/422
  PDF, 66 Kb, File published: Sep 5, 1999
  A bipolar 12V supply from a single +5V input can be developed using a number of conventional approaches. A boost converter is the most logical for the +12V output; however, it cannot be used in some interface-circuit applications. One significant drawback of the boost topology is that, even with the boost converter off, the output voltage approaches the input voltage and does not go to zero. This

  DN-65 Considerations in Powering BiCMOS ICs
  PDF, 100 Kb, File published: Sep 5, 1999
  Bipolar linear integrated circuits have been with us for years in the form of PWM and PFC controllers supervisory circuits and other circuits. Since these devices have traditionally used relatively high-voltage (35V) bipolar processes powering was not a concern. In addition many of these ICs contained high-current protection zeners to keep higher voltages from damaging the devices. With a numb
