LM3677
Overview
The LM3677 step-down DC-DC converter is optimized for powering ultra-low voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7V to 5.5V. It provides up to 600mA load current, over the entire input voltage range.
- 16 µA typical quiescent current 600 mA maximum load capability 3 MHz PWM fixed switching frequency (typ) Automatic PFM/PWM mode switching Available in 5-bump micro SMD package Internal synchronous rectification for high efficiency Internal soft start 0.01 µA typical shutdown current Operates from a single Li-Ion cell battery Only three tiny surface-mount external components required (solution size less than 20 mm2)
- Current overload and Thermal shutdown protecti
