John Seago

Abstract

Optimized DC/DC converter loop compensation, which minimizes the number of large output capacitors, is described.

There is a trade-off between the cost of a few extra passive components and the flexibility that external loop compensation provides. Internal loop compensation is fixed, so it uses fewer passive parts but it also limits the designer’s choice of output capacitors. The output capacitor should be chosen to meet the load requirements, not the regulator requirements. The external loop compensation provided by the LTC1435 family of parts allows the control loop to ...
