TI LM3241TLX/NOPB

转换器，RF 功率放大器2.7V ~ 5.5V0.6V ~ 3.4V

Overview

 The LM3241TLX/NOPB is a DC-DC converter optimized for powering RF power amplifiers(PAs) from a single Lithium-lon cell; however, it may be used in many other applications. It steps down an input voltage from 2.7V to 5.5V to an adjustable output voltage from 0.6V to 3.4V. Output voltage is set using a VCON analog input for controlling power levels and efficiency of the RF PA.

The LM3241 is available in a 6-bump lead-free DSBGA package. A high-switching frequency(6 MHz) allows use of tiny surface-mount components. Only three small external surface-mountcomponents, an inductor and two ceramic capacitors are required.
