  DESIGN IDEAS 2A, 40V, SOT-23 Boost Converter
  Provides High Power in Small Spaces

  Figure 1 shows the LT1935 generating
  5V. Maximum load with VIN = 3.3V is
  1A; from 2.5V the maximum load is
  600mA. Note that the circuit efficiency D1 SW R1

  SHDN The small size eases system design
  in many applications. Large digital
  systems with dense layouts often
  need point-of-load converters to generate secondary logic supplies. With
  a minimum input voltage of 2.3V, the
  LT1935 can convert power from 2.5V,
  3.3V or 5V logic rails to a higher output
  voltage. Even handheld electronics
  such as cell phones, digital cameras
  and music players require peak power
  levels of several watts to drive LEDs, …
