Page 2: Introduction
1 Introduction In light-load conditions, the TPS563203 operates in Eco-mode to enable higher efficiency by varying its switching frequency, the TPS563206 operates in FCCM to maintain constant switching frequency. The main difference is at light loading, but the other behaviors are similar. This user's guide mainly introduces the TPS563203 and includes some TPS563206 features that are different from the TPS563203. -
