LM3262
Overview
The LM3262 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single lithium-ion cell; however, it may be used in many other applications such as USB-powered portable applications. The device 2.5-V to 5.5-V input voltage can be stepped down to an adjustable output voltage range from 0.4 V to 3.6 V.
- 1 Operates from a Single Li-Ion Cell (2.5 V to 5.5 V)
- 6-MHz (Typical) PWM Switching Frequency
- Adjustable Output Voltage (0.4 V to 3.6 V)
- 800-mA Maximum Load Capability (up to 1 A in Bypass Mode)
- High Efficiency (93% Typical at 3.8 VIN, 3.4 VOUT at 500 mA)
- Automatic ECO/PWM/BP Mode Change
- Current and Thermal Overload Protection
- Multi-Function VCON Pin (Eliminates Need for Separate BPEN Control)
- Soft-Start Function
- Small Chip Inductor in 0805 (2012) Case Size
