Designing Non-Inverting Buck-Boost (Zeta) Converters with a Buck P-FET Controller
Constant On-Time (COT) regulators provide a simple, cost-effective way of implementing step-down buck regulators with nearly fixed frequency. COT regulators do not require loop compensation and provide excellent transient performance with minimum design effort. Nonsynchronous operation results in reduced switching frequency at a very light load which delivers higher efficiency than a comparable fixed frequency converter.
