LM3205  
650mA Miniature, Adjustable, Step-Down DC-DC  
Converter for RF Power Amplifiers  
General Description  
Features  
n 2 MHz (typ.) PWM Switching Frequency  
The LM3205 is a DC-DC converter optimized for powering  
RF power amplifiers (PAs) from a single Lithium-Ion cell,  
however they may be used in many other applications. It  
steps down an input voltage from 2.7V to 5.5V to a variable  
output voltage from 0.8V(typ.) to 3.6V(typ.). Output voltage  
is set using a VCON analog input for controlling power levels  
and efficiency of the RF PA.  
n Operates from a single Li-Ion cell (2.7V to 5.5V)  
n Variable Output Voltage (0.8V to 3.6V)  
n Fast Output Voltage Transient (0.8V to 3.6V in 20µs)  
n 650mA Maximum load capability  
n High Efficiency (96% Typ at 4.2VIN, 3.4VOUT at 400mA)  
from internal synchronous rectification  
The LM3205 offers superior performance for mobile phones  
and similar RF PA applications. Fixed-frequency PWM op-  
eration minimizes RF interference. Shutdown function turns  
the device off and reduces battery consumption to 0.01 µA  
(typ.).  
n Current Overload Protection  
n Thermal Overload Protection  
Packages  
n 8-Pin microSMD (Lead Free)  
n 10-Pin LLP  
The LM3205 is available in micro SMD package and LLP  
package. For all other package options contact your local  
NSC sales office.  
Applications  
n Cellular Phones  
n Hand-Held Radios  
n RF PC Cards  
A high switching frequency (2 MHz) allows use of tiny  
surface-mount components. Only three small external  
surface-mount components, an inductor and two ceramic  
capacitors are required.  
n Battery Powered RF Devices  
Typical Application  
20158001
