The LM3218 is a DC-DC converter with inductor which is optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

It steps down an input voltage in the range from 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V.

Includes 2.6 µH Inductor in very small form factor (3mm x.
2.5mm x 1.2mm) 2 MHz (typ. ) PWM Switching Frequency Operates from a single Li-Ion cell (2.7V to 5.5V) Adjustable Output Voltage (0.8V to 3.6V) Fast Output Voltage Transient (0.8V to 3.4V in 25 µs typ. ) 650 mA Maximum load capability High Efficiency (95% typ. at 3.9 VIN, 3.4 VOUT at 400 mA) 8-pin LTCC Package Current Overload Protection Thermal Overload Protection.
