  with 2-Phase Switching to Reduce EMI – Design Note 305

  Introduction
  Advanced electronic systems that use a single voltage
  supply are a thing of the past. Today’s electronic systems require several regulated voltages; even relatively
  simple subsystems need a minimum of two supplies.
  Microprocessors and DSPs, for example, might require
  both a 1.8V core supply and a 3.3V supply for I/O and
  memory. Many board level systems require both 3.3V
  and 5V. Added to this mix is the ever increasing packaging density of electronic products. Voltage regulators
  must п¬Ѓt in a small space in close proximity to sensitive
  circuits, meaning they must be small, efficient and low
  noise. Linear regulators may generate too much heat,
  or be too bulky for some applications, and switching
  regulators present possible EMI problems.
  Circuit Description
  The LTВ®1940 is a dual step-down switching regulator
  that solves these problems for systems requiring two or
  VIN
  7V TO 25V more regulated voltages. Its wide input range, 3.6V to
  25V, accepts a variety of power sources. The low profile
  16-lead TSSOP package has an exposed metal backside, …
