ZHCSH22C January 2009 – November 2017 LM3241
PRODUCTION DATA.
The LM3241 features dynamically adjustable output voltage to eliminate the need for external feedback resistors. The output voltage can be set from 0.6 V to 3.4 V by changing the voltage on the analog VCON pin. This feature is useful in PA applications where peak power is needed only when the handset is far away from the base station or when data is being transmitted. In other instances the transmitting power can be reduced. Therefore the supply voltage to the PA can be reduced, promoting longer battery life. For more information, see the Setting the Output Voltage in the Application and Implementation section. The LM3241 moves into Pulse Skipping mode when the duty cycle is over approximately 92% or less than approximately 15%, and the output voltage ripple increases slightly.
