Texas Instruments (TI) (Dallas, TX) has introduced the industry’s first RF power converters to integrate the MIPI Alliance’s radio frequency front-end (RFFE) digital control interface, a specification that simplifies multi-band and multi-radio communications. The highly efficient LM3263 buck converter and LM3279 buck-boost converter significantly reduce the heat and power consumption in RF power amplifiers, improving battery life and extending talk time in 2G, 3G, and 4G LTE smartphones, tablets and data cards. View an Engineer It video, which outlines how to meet power requirements for the RFFE interface. Features include:
- Compatibility with next-generation RF front end chipsets, power amplifiers and reference platforms.
- Meets voltage and current requirements of 2G, 3G, and 4G, and the LM3279 supports 1-A loads for 3G and 4G.
- Extends battery run-time: 95-percent efficiency; reduces heat dissipation and cuts battery current consumption through average power tracking with dynamically adjustable output voltage.
- High performance, low noise: Designed to meet RF and 3GPP requirements; supports high linearity and high output power, even at low battery voltages.
