  L DESIGN IDEAS Compact Power Solution Overcomes
  Peak Power Limitations in PCMCIABased Pulsed-Load GSM and
  GPRS Applications
  by Timothy Sourdif
  Introduction
  In an increasingly wireless world,
  mobile computing applications are
  driving the need for web-anywhere
  enabled notebook computers. PC Card
  or PCMCIA slot powered GSM/GPRS
  modems are now the standard for these
  applications. During GSM transmission peak currents can exceed 2A, well
  beyond the maximum current capability of the PCMCIA slot. Therefore,
  the modem must be designed to limit
  input power and draw on card-based
