- Closed Loop Compensation of a Synchronous Switching Charger Using bq2472x/3xPDF, 717 Kb, Archivo publicado: sept 25, 2006
Design of the loop compensator is one of the key challenges in the circuit design of a switching charger. This application report presents the internal control loop operation of the bq2472x/3x as well as the external compensator design guideline. The modeling of the nonlinear behavior of a switching charger is based on the state space average model. A design example based on practical specificatio
