Power modules combine 600-V GaN switches with gate drivers
Power switches based on the wide bandgap (WBG) material gallium nitride (GaN) enable excellent efficiency and high switching frequency, starting a new era in power electronics. To support this development, Infineon Technologies AG adds the new CoolGaN IPS family of integrated power stage (IPS) products to its broad portfolio of WBG power devices. The initial […]
Hybrid flyback controller optimized for USB chargers/adapters
Rapid technology and market developments in the fast charger and adapter market continuously challenge designers of power supply systems. To meet the increasing demand for higher power density and energy efficiency, Infineon Technologies AG expands its XDP family by adding the first application-specific standard product based on an asymmetric half-bridge flyback topology. Available in a […]
USB proliferation of capabilities and compatibilities
USB4 represents a significant change from past standards from the USB Implementers Forum (USB-IF). USB4 is based on the Thunderbolt 3 protocol. Support of Thunderbolt 3 interoperability is required on all ports for USB4 docks. It is required for downward-facing ports on hubs and is optional for USB4 hosts and peripheral devices. Like Thunderbolt, USB4 […]

GaN Systems announced the release of the industry’s smallest 100W dual USB-C intelligent PD GaN charger. This turnkey reference design achieves the highest power density of any 100W charger on the market while being the smartest. The charger can balance and appropriately power a variety of plugged-in device power level combinations from a single 100W […]
Transparent conductive glass panels deliver power to USB sockets
Zytronic introduces an innovative method of delivering power through glass invisibly. Called ElectroglaZ, this patent-pending technology opens up new opportunities for low-power devices and applications without using wires. ElectroglaZ can also deliver low power, (sub 50V / 3A), to USB sockets, induction charging pads, motors, fans, security cameras and sensors, air monitoring units in HVAC […]
Power and data adapter meets IEEE 802.3bt PoE-to-USB Type-C spec
There are many consumer, enterprise, and industrial devices today that have a USB Type-C port as the only input power option. While USB-C technology can offer high power and high data rate, it limits the range of the installation to a maximum of three meters from an AC outlet. As Power over Ethernet (PoE) becomes […]
USB Type-C power delivery 3.0 reference design features PPS support
STMicroelectronics has revealed a USB Type-C Power Delivery 3.0 reference design with Programmable Power Supply (PPS) support to accelerate the design of easy-to-use, compact, and efficient power adapters up to 27W with the zero-power operation when no cable is connected. USB PPS helps to save power, and reduce device-charging times and heat dissipation, contributing also to cut […]
