  design features Two Wide Input Range Monolithic Switching Regulators
  Make it Easy to Fit Boost, Flyback, SEPIC and Inverting
  Topologies into Tight Spaces
  Bin Zhang The LT3957 and LT3958 are high power monolithic switching
  regulators that can generate a positive or a negative output
  from a wide range of input voltages. The LT3957 operates
  over an input range of 3V to 40V, making it suitable for
  everything from portable electronics to automotive and
  industrial applications. The LT3958 extends the input
  voltage to 80V for high voltage telecommunications
  supplies. Both produce high power from a small footprint
  as shown by the boost converter layout in Figure 1.
  FEATURES Figure 2. A high efficiency
  and very compact 3V–6V
  input, 12V output boost
  converter VIN
  3V TO 6V By integrating the power MOSFET and
  LDO onto the die, the LT3957 and LT3958
  simplify converter design, shrink the
  solution size and reduce cost when
  compared to non-monolithic solutions. The LT3957 has an integrated
  40V/30mО© N-MOSFET switch with an
  internally programmed current limit of …
