U-150 Applying the UCC3570 Voltage-Mode PWM Controller to Both Off-Line
PDF, 568 Kb, Archivo publicado: sept 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
