LM3253TME/NOPB Product Details

LM3253TME/NOPB Description


A single lithium-ion cell can power several multi-mode 2G, 3G, and 4G RF power amplifiers (PAs) using the DC-DC converter LM3253TME/NOPB. The LM3253 reduces an input voltage from 2.7V to 5.5V to an output voltage that is dynamically adjustable between 0.4V and 3.6V. The output voltage is set by a VCON analog input, which modifies the output voltage to guarantee effective performance at all RF PA power levels. The LM3253TME/NOPB is designed for use with USB datacards.



LM3253TME/NOPB Features


  • 16-bump Thin DSBGA package

  • 3A maximum load current in PWM mode

  • Current and thermal overload protection

  • ACB reduces inductor requirements and size

  • Modulated switching frequency to aid Rx band compliance



LM3253TME/NOPB Applications


  • RF PC cards

  • USB datacards

  • Cellular phones

  • Hand-Held radios

  • Battery-powered RF devices
