General Description

The LM3207 is a DC-DC converter optimized for powering WCDMA / CDMA RF power amplifiers (PAs) from a single Lithium-Ion cell;

however they may be used in many other applications.

It steps down an input voltage from 2.7V to 5.5V to a variable output voltage from 0.8V(typ.) to 3.6V(typ.).

Key Features

2MHz (typ. ) PWM Switching Frequency.
Operates from a single Li-Ion cell (2.7V to 5.5V).
Variable Output Voltage (0.8V to 3.6V).
650mA Maximum load capability.
High Efficiency (95% Typ at 3.9VIN, 3.4VOUT at 400mA) from internal synchronous rectification.
