Buck-boost chargers with 50% greater power density
Texas Instruments (TI) has introduced a small buck-boost charger integrated circuits, which integrate power-path management for maximum power density and universal and fast charging at up to 97% efficiency. The BQ25790 and BQ25792 support efficient charging and ten times lower quiescent current through USB Type-C and USB Power Delivery (PD) ports in small personal electronics, portable medical devices and building automation applications.
CoolSiC 62mm module applications for silicon carbide
Infineon Technologies has added another industry standard package to its CoolSiC MOSFET 1,200V module family. The proven CoolSiC 62mm device has been designed in half-bridge topology and is based on the trench chip technology
Flex uses O-RAN to grow presence in RFPA market
In line with the world’s rapidly advancing 5G cellular wireless networks, Flex Power Modules is working closely with both OpenRAN, and O-RAN Alliance, a global community of more than 160 mobile operators, vendors, and research and academic institutions operating in the Radio Access Network (RAN) industry.
Is the MOSFET figure of merit (FoM) still relevant?
As gate drivers are now capable of efficiently meeting large Qg requirements and faster switching topologies create smaller, more efficient systems, some often ignored parameters have now become system-critical.
