  DESIGN FEATURES LTC1755 Smart Card Interface
  Provides Inductorless Boost
  and Signal-Level Translators by Steven Martin
  Introduction
  Already common in Europe and some
  of the Far East, smart cards may soon
  replace magnetic stripe cards in the
  U.S. The LTC1755 provides a simple
  and complete solution to smart card
  interfacing. Requiring only two bypass
  capacitors and one charge pump
  capacitor, the LTC1755 interfaces
  seamlessly between a smart card
  socket and a host microcontroller. It
  is designed to comply with all of the
  available electrical standards for
  smart card interfacing. Figure 1 shows
  the LTC1755 in a typical smart card
  application.
  Figure 2 shows the block diagram
  of the LTC1755. An internal power
  management unit delivers a selectable 3V or 5V regulated output voltage
  to the smart card. Two unidirectional …
