用于 2G/3G/4G 功率放大器的高电流降压直流/直流转换器

The LM3253 is a DC-DC converter optimized for powering multi-mode 2G/3G/4G RF power amplifiers (PAs) from a single Lithium-Ion cell. The LM3253 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 set through a VCON analog in • High-Efficiency PFM and PWM Modes with Internal Synchronous Rectification\n• Dynamically Adjustable Output Voltage, 0.4V to 3.6V (typ.), in PFM and PWM modes\n• 2.7MHz (average) PWM Switching Frequency\n• Operates From a Single Li-ion Cell (2.7V to 5.5V)\n• Minimum Total Solution Size by Using ;
