应用功能：降压型直流-直流变换器 The LM3203 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 of 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V. The output voltage is set using a VCON analog input and external resistor dividers for optimizing efficiency of the RF PA at various power levels.
