LM3671MF-1.8EV
采用 SOT23-5 和 5 Bump 微型 SMD 封装的 2MHz、600mA 降压 DC-DC 转换器
LM3671MF-1.8EV
概述
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.
