LM3269  
PRODUCT BRIEF  
Seamless-Transition Buck-Boost Converter for 3G and 4G RF Power  
Amplifiers  
General Description  
Features  
The LM3269 is a buck-boost DC/DC converter designed to  
generate output voltages above or below a given input voltage  
and is particularly suitable for single cell Li-ion batteries for  
portable applications.  
Operates from a Single Li-Ion Cell: 2.7V to 5.5V  
Adjustable Output Voltage: 0.6V to 4.2V  
PFM Operation  
750 mA Maximum Load Capability for PVIN 3.0V,  
The LM3269 operates at a 2.4 MHz typical switching frequen-  
cy in full synchronous operation and provides seamless tran-  
sitions between buck and boost operating regimes. The  
LM3269 operates in energy saving Pulse Frequency Modu-  
lation (PFM) mode for increased efficiencies and current sav-  
ings during low-power RF transmission modes.  
VOUT = 3.8V  
2.4 MHz (typ.) Switching Frequency  
Seamless Buck-Boost Mode Transition  
Fast Output Voltage Transition: 1.4V to 3.0V in 10 µs  
High-Efficiency: 95% typ. at PVIN = 3.7V, VOUT = 3.3V,  
at 300 mA  
The power converter topology needs only one inductor and  
two capacitors. A unique internal power-switching topology  
enables high overall efficiency.  
Input Overcurrent Limit  
Internal Compensation  
The LM3269 is internally compensated for buck and boost  
modes of operation, thus providing an optimal transient re-  
sponse.  
12-bump micro SMD Package  
Solution Size = 18.8 mm2  
The LM3269 is available in a 12-bump lead-free micro SMD  
package of size 2.0 mm x 2.5 mm x 0.6 mm.  
Applications  
Power Supply for 3G/4G Power Amplifiers
