Power Loss
Waste heat creates a big headache for system designers. The industry leading efficiency achieved by the CCM250 is 5-10% above existing topologies
used in this power area. This can result in a 70% reduction in generated heat as shown below and enables the overall system to run much cooler and
more reliably.
