Notas de aplicación

  • DN-45 UC3846 UC3856 and UCC3806 Push Pull PWM Current Mode Control ICs
    PDF, 27 Kb, Archivo publicado: sept 5, 1999
    The UC3856 is a pin-for-pin-compatible high-performance bipolar version of the industry standard UC3846. It can replace the UC3846 with few circuit modifications and it features increased speed higher gate-drive current and reduced propagation delays. The UCC3806 is a BiCMOS pin-for-pin compatible ultra-low-power version ideal for battery low-power and high-speed applications. The UCC3806
  • DN-62 Switching Power Supply Topology Voltage Mode vs. Current Mode
    PDF, 66 Kb, Archivo publicado: sept 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.
