LM3243 Datasheet - Texas Instruments

LM3243 Step-Down DC-DC Converter

The LM3243 is a DC-DC converter optimized for powering multi-mode 2G, 3G, and 4G RF power amplifiers (PAs) from a single Lithium-Ion cell. The LM3243 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 set through a VCON.

LM3243 Features

* 1 Input Voltage Range: 2.7 V to 5.5 V

* High-Efficiency PFM and PWM Modes With Internal Synchronous Rectification

* Analog Bypass Function with Low Dropout Resistance (45 mΩ Typical)

* Dynamically Adjustable Output Voltage: 0.4 V to 3.6 V (Typical) in PFM and PWM Mod
