U-93 A New Integrated Circuit for Current Mode Control

Advantages of current-mode control over conventional PWM approaches to switching power converters include automatic feed-forward, automatic symmetry correction, inherent current-limiting, simple loop-compensation, enhanced load-response, and the capability for parallel operation. This application note introduces the first control integrated circuit specifically designed for this topology, defines its operation, and describes practical examples illustrating its use and benefits.
