描述:The LM3241 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion 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 offers three modes of operation. In PWM mode the device operates at a fixed frequency of 6MHz (typ.) which minimizes RF interference when driving medium-to-heavy loads. At light load, the device enters into ECO mode automatically and operates with reduced switching frequency. In ECO mode, the quiescent current is reduced and extends the battery life. Shutdown mode turns the device off and reduces battery consumption to 0.1 μA (typ.).
The LM3241 is available in a 6-bump lead-free DSBGA package. A high-switching frequency (6MHz) allows use of tiny surface-mount components. Only three small external surface-mount components, an inductor and two ceramic capacitors are required.
