LM3208  
650mA Miniature, Adjustable, Step-Down DC-DC  
Converter for RF Power Amplifiers  
General Description  
Features  
n 2 MHz (typ.) PWM Switching Frequency  
The LM3208 is a DC-DC converter optimized for powering  
RF power amplifiers (PAs) from a single Lithium-Ion cell.  
However, it may be used in many other applications. It steps  
down an input voltage in the range from 2.7V to 5.5V to an  
adjustable output voltage of 0.8V to 3.6V. Output voltage is  
set by using a VCON analog input to control power levels and  
efficiency of the RF PA.  
n Operates from a single Li-Ion cell (2.7V to 5.5V)  
n Adjustable Output Voltage (0.8V to 3.6V)  
n Fast Output Voltage Transient (0.8V to 3.4V in 25µs  
typ.)  
n 650mA Maximum load capability  
n High Efficiency (95% typ. at 3.9VIN, 3.4VOUT at 400mA)  
n 8-pin micro SMD Package  
The LM3208 offers superior performance for mobile phones  
and similar RF PA applications. Fixed-frequency PWM op-  
eration minimizes RF interference. A shutdown function turns  
the device off and reduces battery consumption to 0.01 µA  
(typ.).  
n Current Overload Protection  
n Thermal Overload Protection  
Applications  
n Cellular Phones  
n Hand-Held Radios  
n RF PC Cards  
The LM3208 is available in an 8-pin lead-free micro SMD  
package. A high switching frequency (2 MHz typ.) allows use  
of tiny surface-mount components. Only three small external  
surface-mount components, an inductor and two ceramic  
capacitors, are required.
