SANTA ROSA – Keysight Technologies and Rohm Semiconductor announced a PathWave advanced design system-compatible workspace that enables designers to perform pre-compliance testing on virtual prototypes of switched-mode power supply designs.
Keysight teamed with Rohm to make Rohm’s reference design available to mutual customers via Keysight’s website.
"Many of our customers struggle to deal with layout effects when current slew rate in the switched loop exceeds 1A/ns because even tiny parasitic inductances cause ringing. Suppressing EMI is also a big challenge for them," said Ippei Yasutake, group leader at Rohm. "The digital twin gives our customers the insights they need to make changes without running into problems."
"This is going to be a big timesaver for anyone wanting to get the most out of designs that use wide bandgap power devices. The layouts can be hard to tame, and EM extraction is key. This workspace and application-specific tool like PEPro makes things much easier," said Steve Sandler, managing director, Picotest.
