LM3200 Miniature, Adjustable, Step-Down DC-DC Converter with Bypass Mode for RF Power Amplifiers November 2005 LM3200 Miniature, Adjustable, Step-Down DC-DC Converter with Bypass Mode for RF Power Amplifiers General Description The LM3200 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell. It steps down an input voltage of 2.7V to 5.5V to a variable output voltage of 0.8V to 3.6V. The output voltage is set using an analog input ( VCON) for optimizing efficiency of the RF PA at various power levels. The LM3200 offers superior features and performance for mobile phones and similar RF PA applications. Fixedfrequency PWM mode minimizes RF interference.
