LM3279 - Buck-Boost Converter

Description

The LM3279 is a buck-boost DC/DC converter designed to generate output voltages above or below a given input voltage and is particularly suitable for Power Amplifiers operating from single-cell Li-Ion batteries in portable applications.

Features

  • 1 MIPI® RFFE Digital Control Interface.
  • High-Efficiency PFM and PWM Modes with Internal Seamless Transition.
  • Operates from a Single Li-Ion Cell: 2.7 V to 5.5 V.
  • Adjustable Output Voltage:.
  • RFFE Digital Control: 0.4 V to 4.2 V.
  • Analog Control: 0.5 V to 4.2 V.
  • 1-A Maximum Load Capability for VBATT ≥ 3.2 V, VOUT = 3.6 V.
  • 2.4-MHz (typ. ) Switching Frequency.
  • Seamless Buck-Boost Mode Transition.
  • Fast Output Volta.
