Infineon adds GaN (Gallium Nitride) to its power portfolio: CoolGaN™ and GaN EiceDRIVER™ ICs.

The next essential step towards an energy-efficient world lies in the use of new materials and technologies. Wide bandgap semiconductors enable greater power efficiency, smaller size, lighter weight, lower cost, or all together.

Infineon is uniquely positioned in the power semiconductor market, mastering all power technologies from silicon (Si) like CoolMOS™ SJ MOSFETs and IGBTs to wide bandgap materials like silicon carbide (SiC) and gallium nitride (GaN). Its CoolGaN™ devices will significantly enhance designer’s ability to deliver the compact, high performance power systems of the future.

Discover Infineon’s newly launched portfolio of CoolGaN™ switches in SMD packages. Perfectly combinable with parts of the dedicated, single-channel, functional and reinforced isolated GaN EiceDRIVER™ IC family. Enter a new era of efficiency with Infineon.

Benefits

Perfect choice for high frequency and high power density applications

CoolGaN™ 600 V e-mode HEMTs

With CoolGaN™, Infineon launches a GaN enhancement mode high electron mobility transistor (e-mode HEMT) portfolio with industry-leading field performance enabling rugged and reliable systems at an attractive overall system cost.

The e-mode concept is a single-chip solution and hence facilitates further integration either on the chip or package level. Infineon brought its enhancement mode concept to the maturity, required for demanding applications, delivering at the same time the highest performance among all available GaN HEMTs. GaN switch performance features low charge and excellent dynamic performance in reverse conduction compared to silicon FET options.

Infineon’s CoolGaN™ 600 V impresses with highest PFC efficiency (>99.3% for 2.5 kW PFC) and highest density for same efficiency (>160 W/in³ for 3.6 kW LLC with >98% efficiency). The CoolGaN™ portfolio is built around high performing bottom- and top-side cooling SMD packages supporting high frequency operations. Lower parasitics and good thermal performance guarantee to fully exploit the benefits of GaN.

GaN EiceDriver™ IC family

Drive high voltage gallium nitride (GaN) HEMTs with the most robust and efficient single-channel isolated GaN EiceDRIVER™ ICs on the market.

Infineon’s newly launched GoolGaN™ switches portfolio is easy-to-use thanks to a perfectly matching gate driver IC portfolio. By introducing the GaN EiceDRIVER™ IC family, Infineon extends its range of one-channel galvanically-isolated gate driver ICs.

The new components with high gate current for fast turn-on and robust gate-drive topology have been developed to optimize the performance of enhancement mode GaN HEMTs with non-isolated gate (diode input characteristic) and low threshold voltage. Resulting, driver complexity has been significantly reduced (medium effort for design-in) as no more customized drivers are needed.

Target applications

High-voltage bridgeless totem-pole PFC stages and high-voltage resonant LLC stages in telecom and server SMPS
Active-clamping flybacks in AC adapters
Three-phase motor drivers
Class E wireless charging
Class D audio amplifiers
