EVB-EP5357HUI: 1.8V ~ 3.3V @ 600mA, 2.4 ~ 5.5V in

Summary

The EP5357xUI (x = L or H) is a 600mA PowerSOC. The EP5357xUI integrates MOSFET switches, control, compensation, and the magnetics in an advanced 2.5mm x 2.25mm QFN Package. Integrated magnetics enables a tiny solution footprint, low output ripple, low part-count, and high reliability, while maintaining high efficiency. The complete solution can be implemented in as little as 10mm².

A proprietary light load mode (LLM) provides high efficiency in light load conditions.

The EP5357xUI uses a 3-pin VID to easily select the output voltage setting. Output voltage settings are available in 2 optimized ranges providing coverage for typical VOUT settings. The VID pins can be changed on the fly for fast dynamic voltage scaling. EP5357LUI further has the option to use an external voltage divider.
