www.ti.com SNVS426C – NOVEMBER 2006 – REVISED MAY 2013 2-MHz 600-mA Step-Down DC-DC Converter With Mode Control
Check for Samples: LM3676 FEATURES DESCRIPTION The LM3676 step-down DC-DC converter is
optimized for powering low voltage circuits from a
single Li-Ion cell battery and input voltage rails from
2.9V to 5.5V. It provides up to 600mA load current,
over the entire input voltage range. There are several
different fixed voltage output options available as well
as an adjustable output voltage version. 1 2 16ВµA Typical Quiescent Current
