KEY MESSAGES
› LLC w/ CoolMOS™ (380 V-54.3 V): >98% peak
efficiency at 50 W/in
3
density (res freq: 130 kHz)
› LLC w/ CoolGaN™ (380 V-52 V): same efficiency at
140 W/in
3
density (res freq: 350 kHz)
› GaN enables ~3x increase in power density.
When size/weight matters GaN is the choice
› All this is achievable with full SMD solution,
either with DSO-20 or TOLL
› Similar results have been demonstrated for low power
and different ZVS topologies (e.g. PSFB)
