应用须知

  • DN-36 UC1525B/UC1527B Devices - Comparison Summary to UC1525A/27A Devices
    PDF, 19 Kb, 档案已发布: Sep 5, 1999
    The UC1525B and UC1527B are enhanced versions of the previous generation of UC1525A and UC1527A devices. They are pin-for-pin compatible and direct replacements for the A versions in almost all applications. The table in this design note compares the two sets of devices. Significant improvements have been made in the 5.1 V reference voltage and the output drivers as itemized in the table.
  • DN-62 Switching Power Supply Topology Voltage Mode vs. Current Mode
    PDF, 66 Kb, 档案已发布: Sep 5, 1999
    This design note explains the differences between voltage-mode and current-mode switching power supply topologies. It includes a circuit diagram for each mode and suggests criteria for choosing which mode to use.
