  Power Supply Size and Cost
  Introduction Internal Step-Up
  Bias Converter The LT3742 integrates a DC/DC
  step-up converter to generate the
  gate drive voltage for the N-channel
  MOSFETs. The gate drive voltage is
  regulated to (VIN + 7V), which permits
  the use of inexpensive off-the-shelf
  5V gate-drive N-channel MOSFETs,
  offering higher efficiency than sublogic-level gate-drive MOSFETs. The
  gate driver is capable of driving large,
  low RDS(ON), standard level, N-channel
  MOSFETS without the need for a gate
  drive buffer.
  Integrating the step-up converter
  also allows low dropout and 100% duty
