The Adaptive On-Time controller has multiple advantages. No external compensation components are required since there is no error amp used in the control architecture. Instead, the slow error amp has been replaced by a fast comparator that provides instantaneous response to a load transient. This further helps reduce the required output capacitance and hence the total solution size as such. Unlike comparable constant on-time and hysteretic control architectures, adaptive on-time architecture provides a predictable, pseudo fixed switching frequency making it easy for designers to locate and diagnose noise issues, if any, in their application. All Semtech EcoSpeed, Adaptive on-time products come with an external resistor adjustable on-time feature that helps designers use multiple products on the same board to generate multiple rails with switching frequencies close to each other.
