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.
- Integrated Vref LDO.
- Regulated LDO Output up to 10mA max.
- Fast 3uS Vref LDO On/Off Time.
- 9-pin micro SMD Package.
- Current Overload Protection.
- Thermal Overload Protection.
