LM3673 Datasheet
LM3673 Datasheet (National Semiconductor)
National Semiconductor
The LM3673 step-down DC-DC converter is optimized for powering low voltage circuits from a single Li-Ion cell battery and input voltage rails from 2.7V to 5.5V. It provides up to 350mA load current, o.
and performance for mobile phones and similar portable systems. The LM3673 uses intelligent automatic switching between PWM and PFM for better efficiency. During PWM mode, the device operates at a fixed-frequency of 2 MHz (typ). Hysteretic PFM mode extends the battery life by reducing the quiescent .
