Skyworks Solutions Inc. Si82Fx Evaluation Kits
Skyworks Solutions Inc. Si82Fx Evaluation Kits are designed to evaluate and test the functionality and performance of the Si82Fx isolated gate drivers. The evaluation board can be used in standalone mode with an oscilloscope and the onboard dummy capacitive load, or it can be connected to a switch mode power supply (SMPS) controller and external power MOSFETs to conduct a system-level evaluation.
The Skyworks Si82Fx dual-channel isolated gate drivers feature variable current drive (VCD) and universal input in WB SOIC14 (6kVRMS isolation), NB SOIC16 (3.75kVRMS isolation), and LGA13 (2.5kVRMS isolation) packages.
In systems where the controller handles overlap protection and dead time control, the Si82Ex kit universal input attribute permits the chip to function as two independent drivers in any high-side + high-side, low-side + low-side, or high-side + low-side topologies.
The kits cover a wide variety of Si82Fx drivers. Nonetheless, depending on the driver IC on the board, some features are only available on specific boards.
The VCD feature (only available on Si82Fx) allows adjusting the rising/falling edge driving strength to eliminate external gate resistors. The chip also integrates input signal overlap protection and dead time insertion to simplify controller complexity.
