Description for the LM3242

The LM3242 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 2.7 V to 5.5 V to an adjustable output voltage from 0.4 V to 3.6 V. Output voltage is set using a VCON analog input for controlling power levels and efficiency of the RF PA.

The LM3242 offers five 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, 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). In low-battery condition Bypass mode reduces the voltage dropout to less than 50 mV (typical). The part also features a Sleep mode.

The LM3242 is available in a 9-bump lead-free DSBGA package. A high switching frequency (6 MHz) allows use of only three tiny surface-mount components: one inductor and two ceramic capacitors.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
