After in June launching what it claimed was the lowest-resistance 650V-blocking-voltage transistor (specifying an Rdson as low as 15mOhm), VisIC Technologies Ltd of Rehovot, Israel, a fabless developer of devices based on gallium nitride (GaN) metail-insulator-semiconductor high-electron-mobility transistors (MISHEMTs) founded in 2010, has now delivered evaluation boards (EB) and samples of its ALL-Switch (Advanced Low-Loss Switch) to leading customers, allowing users to perform extensive testing confirming the switching parameters.
The evaluation board includes gate driver and switching control logic based on commercially available components. ALL-Switch is configured for hard switching on the evaluation board and can switch a 400V load with greater than 30A currents at over 500kHz.
VisIC says that its technology solves problems that have limited devices from simultaneously achieving step-function reductions in conduction and switching losses for power conversion systems that can benefit from high switching speeds.
VisIC will soon also announce details of a half-bridge reference design.
