LM3671MF-1.8EV
2MHz、600mA 降圧 DC-DC コンバータ、SOT23-5 /5 バンプ Micro SMD パッケージ
LM3671MF-1.8EV
概要
The LM3671 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.
