The LM3209-G3 is buck-boost DC/DC converter designed to generate output voltages above or
below a given input voltage. It is particularly suitable for single-cell Li-ion batteries for
The LM3209-G3 operates at a 2.4 MHz typical switching frequency in full synchronous
operation providing seamless transitions between buck and boost operating modes.
The power converter topology needs only one external inductor and two capacitors. Five
internal power switches enable high overall efficiency.
The LM3209-G3 is internally compensated for buck and boost modes of operation, thus
providing an optimal transient response.
The LM3209-G3 is available in an 12-bump lead-free DSBGA package of size 2.0 mm × 2.5 mm
× 0.6 mm.
