Using a Current Mode PWM Controller in Voltage Mode
by Dimitry Dobrenko, Engineer-Specialist Power Supply Design, Alvarion, Petach, Tikva Israel, Power Electronics Technology, Jan 01 2004
Focus:
Although PWM controllers with current-mode control are more common than those with voltage-mode control, voltage-mode control is recommended under certain application conditions. For these cases. it's possible to configure a current-mode PWM controller to operate under voltage-mode control.
What you’ll learn:
- How to operate a current-mode PWM controller in voltage mode
- How to configure the UCC2808A controller to operate in voltage mode without adding many components
- How to know when to apply voltage-mode control
