  • Modeling Analysis and Compensation of the Current-Mode Converter
    PDF, 189 Kb, 档案已发布: Sep 5, 1999
    As current-mode conversion increases in popularity several peculiarities associated with fixed-frequency peak-current detecting schemes have surfaced. These include instability above 50% duty cycle a tendency towards subharmonic oscillation non-ideal loop response and an increased sensitivity to noise. This application note attempts to show that the performance of any current-mode converter c
  • DN-45 UC3846 UC3856 and UCC3806 Push Pull PWM Current Mode Control ICs
    PDF, 27 Kb, 档案已发布: Sep 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
  • U-93 A New Integrated Circuit for Current Mode Control
    PDF, 411 Kb, 档案已发布: Sep 5, 1999
    Advantages of current-mode control over conventional PWM approaches to switching power converters include automatic feed-forward automatic symmetry correction inherent current-limiting simple loop-compensation enhanced load-response and the capability for parallel operation. This application note introduces the first control integrated circuit specifically designed for this topology defines
  • 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.
