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 вЂњsupply marginingвЂќ or вЂњvoltage margining.вЂќ 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 …
