应用须知

  • Programming the UCC3809 for 90% Maximum Duty Cycle Clamp
    PDF, 44 Kb, 档案已发布: Jun 4, 2001
    Normally, the UCC3809 programmable duty cycle clamp feature is limited to 70% maximum duty cycle. The described technique shows how the maximum duty cycle clamp can be programmed to achieve a 90% on-time of the switching period.
  • U-168 Implementing a Practical Off-line Lithium-Ion Charger Using the UCC3809
    PDF, 579 Kb, 档案已发布: Sep 5, 1999
    The UCC3809 family of BCDMOS economy low-power integrated circuits contains all the control and drive circuitry required for off-line and isolated DC-to-DC fixed-frequency current-mode switching power supplies with minimal external parts count. The UCC3956 family of Switch-Mode Lithium-Ion Battery Charger Controllers accurately controls lithium-ion battery charging with a highly efficient average
  • DN-89 Comparing the UC3842, UCC3802, and UCC3809 Primary Side PWM Controllers
    PDF, 75 Kb, 档案已发布: Sep 5, 1999
    Despite the fact that the UC3842 and the UCC3802 PWM Controllers are pin-for-pin compatible, they are not drop-in replacements for each other. Designed as the next generation '42, the UCC3809 also has differences that prevent a simple drop-in substitute. This design note will help the user change from either the UC3842 or the UCC3802 to the UCC3809 in an existing design. A table identifies the mos
  • U-165 Design Rvw: Isolated 50 W Flyback Converter Using UCC3809 and UC3965
    PDF, 266 Kb, 档案已发布: Sep 5, 1999
    The flyback power stage is a popular choice for single and multiple output DC-to-DC converters at power levels of 150W or less. Without the output inductor required in buck-derived topologies, such as the forward or push-pull converter, the component count and cost are reduced. This application note will re-view the design procedure for the power stage and control electronics of a flyback converte
  • 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.
