LM3262 - Step-Down DC-DC Converter

Description

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.

Features

  • 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 Fun.
