Design of a High Temperature Switched-Mode Power Supply Employing a V2 Control Mechanism

Focus:

Study uses Spice simulation to demonstrate the feasibility of a switched-mode power supply (a buck converter) using V2 (V-squared) control that can operate at temperatures up to 225 degrees C. Operation of V2 control scheme in a buck converter is described and specifications for a V2 controller IC are given.

What you’ll learn:

• How to conceptually design a buck converter using V2 control for extreme high temperature operation
• How to design power supplies using V2 control
• How to identify challenges in the design of power supplies for extreme high-temperature operation
