Silicon Carbide Could Improve MOSFET Performance

ON Semiconductor claims that new SiC MOSFETs boost performance and reliability compared to silicon.
ON Semiconductor has introduced two lines of wide bandgap silicon carbide (WBG SiC) MOSFETs. The design of these MOSFETs is an improvement over traditional builds and offers levels of performance that ON claims were not possible with silicon MOSFETs.

These MOSFET families are designed for use in a variety of applications, like solar power inverters, onboard charging for electric vehicles, uninterruptible power supplies (UPS), server power supplies and EV charging stations.
The 1200V and 900V N-channel SiC MOSFETs also provide faster switching performance and better reliability when compared to silicon. An intrinsic diode with low reverse recovery charge further reduces power losses, boosts operating frequencies, and increases the power density of the overall system.
The 1200V series is rated at up to 103A (I
D max), while the 900V line carries ratings as high as 118A. For applications requiring higher currents, the SiC MOSFETs can be operated in parallel due to their positive temperature coefficient/temperature independence.
"If design engineers are to meet the challenging efficiency and power density goals that modern renewable energy, automotive, IT and telecom applications demand, then they require high performance, high reliability MOSFET devices," said Gary Straker of ON Semiconductor. "ON Semiconductor’s WBG SiC MOSFETs extend performance beyond what was possible with silicon devices, delivering lower losses, higher operating temperatures, faster switching, improved EMI and better reliability."
Overall, high frequency operation can be enhanced by the MOSFETs’ small chip size, which leads to a lower device capacitance and reduced gate charge (as low as 220nC), reducing switching losses when operating at high frequencies. These enhancements help improve efficiency, reduce EMI when compared with silicon-only MOSFETs, and allow for the use of fewer (and smaller) passive components.

New USB-C Controllers Aim to Improve Next-Gen PCs and Notebooks

Cypress Semiconductor announced its latest series of USB-C controllers: the EZ-PD CCG6DF and CCG6SF. These dual- and single-port USB-C controllers have a smaller size and lower cost to help shrink the design footprint of USB-enabled devices. The company’sEZ-PD controllers also support the USB4 standard as well as the Intel Thunderbolt platforms.
The adoption of the USB-C standard is growing across the world as an increasing number of manufacturers incorporate the technology into their lines of devices and accessories. There are several reasons for this trend, notably USB-C’s ability to simultaneously power devices and transmit data using the same cable and reversible connector.

 


The EZ-PD CCG6DF and CCG6SF include multiple new features like a VBUS provider path load switch for power with fault protection and an embedded 32-bit Arm Cortex-M0 processor with 64-KB flash. This processor enhances programmability and enables firmware upgrades to support USB4, which improves the data transfer rate to 40Gb/s and allows simultaneous support of USB 3.2, DisplayPort and PCIe.
USB-C powers devices up to 100W and provides the consolidation of different interfaces on the same port.
"As the leading supplier of USB-C controller solutions, our deep system-level understanding allows us to continue to provide highly integrated solutions that maximize value for ourcustomers," said Ajay Srikrishna, vice president of Cypress’ Wired Connectivity Business Unit. "Cypress’ latest CCG6DF and CCG6SF controllers provide the performance, programmability, and field-proven USB Power Delivery features needed by makers of notebooks, desktops, and all-in-one PCs."
The CCG6DF and CCG6SF controllers are now sampling to OEMs and will be in volume production beginning in Q3 2020. They are available in configurations including 96-pin BGA and 48-pin QFN packages.
