Application Notes

  • DN-26 UC3842A Low-Cost Start-up and Fault Protection Circuit
    PDF, 155 Kb, File published: Sep 5, 1999
    The UC1842/3/4/5 family of control ICs can implement off-line or DC-to-DC fixed-frequency current-mode control schemes with a minimal external parts count. This design note describes a circuit with low startup current (less than 0.5mA) MOSFET-compatible undervoltage lockout thresholds programmable restart-delay HICCUP fault protection auxiliary 5V precision reference and overvoltage/overtemper
  • 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
  • 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-27 UC1842/UC1842A Family - Summary of Functional Differences
    PDF, 21 Kb, File published: Sep 5, 1999
    The UC1842A/3A/4A/5A family of control ICs is a pin-for-pin compatible improved version of the UC3842/3/4/5 family. Providing the necessary features to control current-mode switched-mode power supplies this device has been improved for higher frequency off-line power supplies.

  • DN-42A Design Considerations for Transitioning from UC3842 to the New UCC3802
    PDF, 42 Kb, File published: Sep 5, 1999
    The UCC3802 offers numerous advantages that allow the power supply design engineer to meet requirements for lower power for battery-operated equipment higher switching frequencies for reduced magnetics size higher levels of circuit integration for improved reliability and lower cost. The UCC3802 family of devices is pin-out compatible with the UC3842 and UC3842A families; however it is not plu
  • U-100A UC3842/3/4/5 Provides Low-Cost Current-Mode Control
    PDF, 507 Kb, File published: Sep 5, 1999
    The fundamental challenge of power supply design is to realize simultaneously two conflicting objectives: good electrical performance and low cost. The UC3842/3/4/5 control ICs are integrated pulse-width modulators (PWMs). These inexpensive IC controllers provide all the performance advantages of current-mode operation. In addition the UC3842 series is optimized for efficient power-sequencing of
