Features

* n n n n n n n n n 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 25µs typ. ) 650mA Maximum load capability High Efficiency (95% typ. at 3.9VIN, 3.4VOUT at 400mA) 8-pin micro

Applications

* 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. Output voltage is set by using a VCON analog input to control power levels and efficiency of the RF PA. The LM3208 offers superior performance for mobile phones and similar RF PA applicati
