ICERGi has taken the totem-pole PFC design one stage further through its new digital control and drive silicon IC70101 and IC70001. These offer a simplified high-side drive arrangement enabling the use of MOSFET switches instead of wide bandgap devices. This results in a 4 times inductor size improvement at a lower BOM cost than current GaN/SiC based designs.
ICERGi’s control and driver silicon is off-the-shelf, and deliverable through a variety of business models.
Some of the key control and drive components can be found on Bodo’s eNewsletter.
