The LM3202 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 1.3V to 3.16V. Output voltage is set using a V_CON analog input for controlling power levels and efficiency of the RF PA.

The LM3202 offers superior performance for mobile phones and similar RF PA applications. Fixed-frequency PWM operation minimizes RF interference. Shutdown function turns the device off and reduces battery consumption to 0.01 A (typ.).

The LM3202 is available in a 8-pin lead free micro SMD package. 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.
