When designing switched-mode power supplies, the main figures of merit are efficiency, size, and cost,.These parameters are closely related. Power density is a key metric for power system designers: it is a measure of how much power can be processed in a given space. There are major limitations to achieving the more compact and efficient power solutions. Overcoming power losses and thermal performance challenges requires innovations in switching properties, IC packaging, circuit design and integration.
GaN power FETs are radically changing the power engineering world by enabling high-speed, increased efficiency and higher power density never before possible with silicon MOSFETs
MasterGaN devices offer:
- High efficiency due to reduction of switching and conduction losses and elimination of reverse recovery loss
- Higher switching frequency, enabling higher power density solution, up to four times smaller than with silicon MOSFETs. This improvement translates in smaller, lighter, very compact power supply
- MasterGaN integrates in one package one half-bridge high voltage driver and two GaN switches. This integration allows to ease application design, simplifies PCB layout and creates more robust solution.
- Identify the advantages of using GaN technology in high voltage converter architectures
- Explore the benefits of integrating GaN half-bridge with gate drivers and bootstrap diode
