Pair up for the best performance!

Infineon’s superjunction MOSFETs go hand-in-hand with perfectly matching gate driver ICs

If you know Infineon as the leading supplier of superior quality power MOSFETs, you’re totally right!

But this is only half of the story. For all its high voltage switches Infineon also offers perfectly matching gate driver ICs with all kind of configurations, voltage classes, isolation levels, protection features, and package options. As such, you as customer benefit from faster switching and optimized overall system performance.

Infineon develops its gate driver IC solutions leveraging the company’s application expertise and advanced tech know-how, making them the perfect fit for a multitude of applications.

Given the trend towards higher power density in the high power SMPS market, faster switches are needed. At the same time, ways must be found to overcome design challenges like parasitics, board limitations and possible thermal issues. Infineon’s 4-pin Kelvin Source CoolMOS™ SJ MOSFETs in total harmonic distortion (THD) and surface mounted device (SMD) packages combined with the EiceDRIVER™ gate driver IC portfolio are the right solution to solve your design problems.

Pair up now, and enjoy the convenience of getting all out of one expert’s hand!

NEW: Take the opportunity to discover Infineon’s newly launched 1EDNx550 EiceDRIVER™ single-channel, low-side, non-isolated gate driver IC family with truly differential control inputs.
 

1EDN TDI - 1-channel, low-side, non-isolated gate driver ICs with truly differential inputs

Infineon’s newly launched EiceDRIVER™ 1EDN7550 and 1EDN8550 single-channel, low-side, non-isolated gate driver ICs have truly differential inputs. Hence, they are perfectly suited for SMPS with ground shift challenges. Characteristically, their control signal inputs are largely independent from the ground potential. Only the voltage difference between the input contacts is relevant. This prevents false triggering of power MOSFETs.

Target applications: server, telecom, DC-DC converters, telecom bricks, power tools, industrial SMPS, wireless charging, and solar micro inverter.
