Application Notes
- U-110 1.5 Mhz Current Mode IC Controlled 50-Watt Power SupplyPDF, 298 Кб, Файл опубликован: 5 сен 1999
The UC3825 family of PWM control ICs is optimized for high-frequency switched-mode power-supply applications. This application note describes the development of a 1.5 MHz current-mode IC-controlled 50W power supply. Push-pull topology is used for this DC-to-DC converter application of +48V input to +5V at 10A output. Increases in switching speed and dynamic performance are made possible by the U - U-111 Practical Considerations in Current Mode Power SuppliesPDF, 787 Кб, Файл опубликован: 5 сен 1999
This application note explains the numerous PWM functions and ways to maximize their usefulness. It covers practical circuit design considerations such as slope compensation gate drive circuitry external control functions synchronization and paralleling current-mode controlled modules. Circuit diagrams and simplified equations are included.
