Description
General part information
LM3241 Series
The LM3241 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell. The device can also be used in many other applications. The device steps down an input voltage from 2.7 V to 5.5 V to an adjustable output voltage from 0.6 V to 3.4 V. The 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 6 MHz (typical) which minimizes RF interference when driving medium-to-heavy loads. At light-load conditions, 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 (typical).
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-mount components, an inductor and two ceramic capacitors are required.
