SNVS837B – JUNE 2013 – REVISED APRIL 2016 LM3263 High-Current Step-Down DC-DC Converter With MIPI® RF Front-End
Control Interface for RF Power Amplifiers
1 Features 1 3 Description
The LM3263 is a DC-DC converter optimized for
powering multi-mode multi-band RF power amplifiers
(PAs) from a single lithium-ion cell. The LM3263
steps down an input voltage from 2.7 V to 5.5 V to a
dynamically adjustable output voltage of 0.4 V to
3.6 V. The output voltage is externally programmed
through the RFFE Digital Control Interface and is set
to ensure efficient operation at all power levels of the
RF PA. В® MIPI RFFE Digital Control Interface
Operates from a Single Li-Ion Cell: 2.7 V to 5.5 V
Dynamically Adjustable Output Voltage: 0.4 V to
3.6 V (Typical) in PFM and PWM Modes
High-Efficiency PFM and PWM Modes With
Internal Seamless Transition …
