illustrate

The LM3208 is a DC-DC converter optimized for RF power amplifiers (PAs) powered from single-cell lithium-ion batteries. However, it can be used in many other applications. Adjustable output voltage from 2.7V to 5.5V to 0.8V to 3.6V in the input range from the bottom range. The output voltage is by using a VCONThe analog inputs control the power level and efficiency of the RF power amplifier.

The LM3208 mobile phone and similar RF PA applications offer superior performance. Fixed frequency PWM operation minimizes RF interference. The shutdown function shuts down the device and reduces power consumption to 0.01μA (typical).

The LM3208 is available in an 8-pin lead-free microSMD package. High switching frequency (2 MHz typical.) Allows the use of tiny surface mount components. Only three small external surface mount components, an inductor and two ceramic capacitors, are required.
