LM3671MF-1.5EV: 1.5V @ 600mA 2.7 ~ 5.5Vin

Summary

The LM3671MF-1.5EV evaluation board is a working demonstration of a step down DC-DC converter. The application note contains information about the evaluation board. The LM3671 step-down DC-DC converter is optimized for powering ultra-low voltage circuits from a single Li-Ion cell or 3 cell NiMH/NiCd batteries. It provides up to 600 mA load current, over an input voltage range from 2.8V to 5.5V. There are several different fixed voltage output options available as well as an adjustable output voltage version. This device offers superior features and performance for mobile phones and similar portable applications with complex power management systems.
