Here are several design tools, simulators, controllers, and GUIs that were on display on the show floor at this year's APEC.

The ADP1055 evaluation board features an isolated full bridge topology with full bridge secondary side rectification operating at 125kHz switching frequency. Its rated output is 12V, 20A with an input ranging from 38-60VDC.

The ADP1055 digital controller as the main controller provides various functions such as PWMs, voltage and current sensing, feedback, etc. It also provides protection features such as OCP, OVP, and OTP. Advanced features such as black-box, active snubber, constant current mode, double update rate, and digital compensation are self-contained in the ADP1055.

Figure 2: It is truly graphic and interactive.

Here, Analog Devices digital power team shows off their designer-friendly GUI that is used to program the ADP1055. Power design engineers with no prior programming experience can use the software to monitor and quickly adjust functions like PWM timings, frequency, filter settings, protection limits, etc.

Figure 3: Mr. Potato head was able to power an Analog Devices digital isolator.

We were anxious to see if the potato would be able to keep the device running for the entire length of the exhibit. I believe they did not need any more potatoes.
