LM3207 Overview
Key Specifications
Mount Type: Surface Mount
Pins: 9
Operating Voltage: 5.5 V
Output Type (varies by manufacturer): Adjustable
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
