 628 views

This application note presents a detail modeling and design of current mode control boost converters operating in the continuous conduction mode (CCM). Based on the derived small signal models, the design of a lag compensator for current mode control boost converters will be detailed. The LM3478 boost controller will be used in the example. Simulation and hardware measurement of frequency responses will be shown.
