Texas Instruments TPS566242 | Demoboard TPS566242EVM

Description

In light-load conditions, the TPS566242 operates in Eco mode to enable higher efficiency by varying its switching frequency. The TPS566247 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 TPS566242 and includes some features about the TPS566247 that are different from the TPS566242.
