  DESIGN IDEAS High Efficiency Synchronous Boost
  Converter Provides Output Load
  Disconnect and Soft-start in
  ThinSOT Package
  by Ashish Kirtania
  In a typical boost converter architecture, the inductor and the Schottky
  diode or the body-diode of the PMOS
  rectifier constitute a forward conduction path from input to output
  whenever the output is lower than
  the input (e.g., during start-up and
  shutdown). As a result, the output capacitor usually draws a heavy inrush of
  current from the input supply during
  start-up. Likewise, in shutdown, the
  output capacitor holds the output at
  a potential equal to the input supply
  voltage minus a forward diode drop.
  Linear Technology’s new LTC3429
  solves both of these problems by
  eliminating any forward conduction
  through the body diode of the synchronous PMOS switch. This enables the
  part to achieve output load disconnect
  by allowing the output voltage to go
  to zero during shutdown, drawing no …
