应用须知
- U-150 Applying the UCC3570 Voltage-Mode PWM Controller to Both Off-LinePDF, 568 Kb, 档案已发布: Sep 5, 1999
The UCC3570 families of pulse-width modulators are for application in isolated switching supplies using primary-side control and a voltage-mode feedback loop. BiCMOS processing provides higher switching frequencies at lower quiescent current drain, while including innovations in both performance and protection features. Its versatility is demonstrated with the description of a 50W, wide input-volt - DN-62 Switching Power Supply Topology Voltage Mode vs. Current ModePDF, 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.
