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
