  DESIGN FEATURES Voltage Margining Made Easy
  by Jeff Heath
  Introduction Linear Technology has introduced two
  devices that simplify supply margin
  testing and are particularly well suited
  for multiple power supply applications.
  The LTC2920-1 is a single power supply margining controller packaged in
  a 5-lead SOT-23. The LTC2920-2 is a
  dual power supply margining controller packaged in an 8-lead MSOP. Both
  parts provide an easy and accurate way
  to accomplish onboard power supply
  margining with a minimum of design
  time and board space. testing is often called “supply margining” or “voltage margining.” The testing
  is typically accomplished by forcing
  the power supply modules or DC/DC
  converters in the system to В±5% of
  their nominal voltage. Once the supply
  voltage has settled at the margined
  voltage, the system performance can
  be evaluated. Figure 1 shows typical
  rise and fall times for voltage margining waveforms. Typical Applications
  Figure 2 shows how the 5-lead SOT23 LTC2920-1 controls a LTC1435A
  switching regulator by sourcing or …
