1.4 Device Information

Synchronous buck converter TPS56425X is used in the EVM to achieve the high-efficiency power delivery and voltage conversion. The TPS564252 operates in Eco-mode, which maintains high efficiency during light loading. The TPS564257 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. The TPS564255 operates in OOA mode, which prevents audio noise generation.
