  DESIGN IDEAS L Low Power Boost Regulator with
  Dual Half-Bridge in 3mm Г— 2mm DFN
  Drives MEMS and Piezo Actuators
  by Jesus Rosales Introduction
  Advances in manufacturing technology have made it possible for actuators,
  sensors, RF relays, and other moveable
  parts to be manufactured at a very
  small scale. These devices, referred
  to as MEMS (micro-electro-mechanical systems) or micro-machines, are
  finding their way into daily life in
  applications unheard of just a few
  years ago. MEMS are used in automotive, military, medical and consumer
  product applications.
  Many types of MEMS devices consume very little power to operate and
  generally require the use of two support circuits, a step-up converter and a
  dual half-bridge driver. These support
  circuits must be very small and highly
  efficient to keep pace with ever-shrinking MEMS applications. To this end,
  the LT8415 integrates the step-up
  converter power switch and diode and
  the dual half-bridge driver in a 12-pin,
  3mm Г— 2mm DFN package. Its novel
  switching architecture consumes very …
