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• Analog Bypass Function with Low Dropout Resistance (45 mΩ typ.)\n• Dynamically Adjustable Output Voltage, 0.4V to 3.6V (typ.), in PFM and PWM modes\n• 3A Maximum Load Current in PWM Mode\n• 2.7MHz (average) PWM Switching ;
