FEATURES  
DESCRIPTION  
The LM3263 is a DC-DC converter optimized for  
•
MIPI® RFFE Digital Control Interface  
23  
powering multi-mode multi-band RF power amplifiers  
(PAs) from a single Lithium-Ion cell. The LM3263  
steps down an input voltage from 2.7V to 5.5V to a  
dynamically adjustable output voltage of 0.4V to 3.6V.  
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.  
•
High-Efficiency PFM and PWM Modes with  
Internal Seamless Transition  
•
•
Operates from a Single Li-Ion Cell: 2.7V to 5.5V  
Dynamically Adjustable Output Voltage: 0.4V  
to 3.6V (typ.) in PFM and PWM Modes

•
2.5A Maximum Load Current in PWM Mode  
2.7 MHz (typ.) Switching Frequency  
ACB (reduces inductor requirements and size)  
Internal Compensation  
The LM3263 operates in modulated frequency PWM  
mode producing a small and predictable amount of  
output voltage ripple. PWM mode enables best  
meeting power requirements and stringent spectral  
compliance, with the minimal amount of filtering and  
excess headroom. When operating in PFM mode, the  
LM3263 enables the lowest current consumption  
across PA output power level settings and therefore  
maximizes system efficiency.  
Current and Thermal Overload Protection  
16-bump DSBGA Package  
Very small Solution Size: approx. 9.8 mm2  
APPLICATIONS  
The LM3263 has a unique Active Current assist and  
analog Bypass (ACB) feature to minimize inductor  
size without any loss of output regulation for the  
entire battery voltage and RF output power range,  
until dropout. ACB provides a parallel current path,  
when needed, to limit the maximum inductor current  
to 1.45A (typ) while still driving a 2.5A load. The  
analog bypass feature also enables operation with  
minimal dropout voltage.
