Description
General part information
LM3269 Series
The LM3269 is buck-boost DC-DC converter designed to generate output voltages above or below a given input voltage and is particularly suitable for portable applications powered by a single-cell Li-ion battery.
The LM3269 operates at a 2.4-MHz typical switching frequency in full synchronous operation and provides seamless transitions between buck and boost operating regimes. The LM3269 operates in energy-saving Pulse Frequency Modulation (PFM) mode for increased efficiencies and current savings during low-power RF transmission modes.
The power converter topology needs only one inductor and two capacitors. A unique internal power switch topology enables high overall efficiency.
