The migration from electromechanical energy metering to solid-state energy metering is driven by demands for advanced functionality, higher accuracy and lower cost. Many of these benefits were discussed in a previous Analog Feedback article (see ...
A software-driven calibration routine for a
power-supply controller IC eliminates the time consuming
and costly problems of manual
calibration and results in more reliable, more
accurate performance in the field.
With the California Energy Commission mandating
minimum levels of efficiency for external power supplies sold in the state, many linear
supplies will need to be redesigned using switch-mode technology.
Using finite element analysis (FEA) techniques, a
simulation tool generates frequency-dependent
models of integrated magnetic components,
accounting for the materials and winding layout
of the magnetic component.
Typically, dc-dc converters are designed for use at a fixed output voltage. Some applications, such as dual data rate (DDR) memory bus and other high-speed logic bus terminations, require the output voltage to be a fixed percentage of an external...
