FEATURES  
DESCRIPTIO  
■
Optimized Features for WCDMA Handsets  
The LTC®3444 is a highly efficient, fixed frequency, buck-  
boost DC/DC converter, which operates from input volt-  
ages above, below, and equal to the output voltage. The  
topology incorporated in the IC provides a continuous  
transferfunctionthroughalloperatingmodes, makingthe  
product ideal for a single Lithium-Ion or multi-cell  
applicationswheretheoutputvoltagecanvaryoverawide  
range.  
■
Regulated Output with Input Voltages  
Above, Below, or Equal to the Output  
■
0.5V to 5V Output Range  
■
Up to 400mA Continuous Output Current From  
a Single Lithium-Ion Cell  
■
Minimal External Components  
■
1.5MHz Fixed Frequency Operation  
■
Internal Loop Compensation for Fast Response  
The LTC3444 has been optimized for use in 3G WCDMA  
applications. A unique design yields high efficiency at  
very low output voltages while also eliminating external  
components. The high speed error amplifier provides the  
fast transient response required to slew the RF power  
amplifier from standby to transmit and transmit to stand  
by power levels. Output overvoltage protection protects  
the RF power amplifier.
