  advertisement ThinSOT Micropower Buck Regulator Has Low Output Ripple
  Design Note 373
  Keith Szolusha
  Introduction
  High voltage monolithic step-down converters simplify
  circuit design and save space by integrating the highside power switch into the device. In most cases, the
  switch is an n-type transistor (NMOS or NPN) with a
  boot-strapped drive stage, requiring an external boost
  diode and capacitor as well as the main catch diode,
  complicating the applications circuit. If the load is light, the IC alternates between micropower
  and switching states to keep the output in regulation
  (Figure 3a). Hysteretic mode allows the IC to provide
  single switch-cycle bursts for the lowest possible lightload output voltage ripple ( …

  DESIGN IDEAS Low Ripple Micropower SOT-23 Buck
  Regulator with Integrated Boost and
  Catch Diodes Accepts Inputs to 40V
  by Leonard Shtargot Introduction
  The LT3470 is a micropower buck
  regulator that integrates a 300mA
  power switch, catch diode and boost
  diode into a low profile 8-Pin ThinSOT
  package (see Figure 1). The combination of single cycle Burst Mode and
  continuous operation allows the use
  of tiny inductor and capacitors while
  providing a low ripple output to loads
  of up to 200mA. With its wide input
  range of 4V to 40V and low quiescent
  current of 26ВµA (12V in to 3.3V out) the
  LT3470 can regulate a wide variety of
  power sources, from 2-cell Li-Ion batteries to unregulated wall transformers
  and lead acid batteries. 3 BIAS 7 +
