CoolGaN™ 600V E-mode HEMTs - Key Features & Benefits (Highest Efficiency & Density Levels in SMPS)

Infineon's CoolGaN™ is the most reliable and highly qualified GaN solution currently available in the market and offers a predicted lifetime of more than 15 years, with a failure rate less than 1Fit. 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™ 600V impresses with highest PFC efficiency (>99.3% for 2.5kW PFC) and highest density for same efficiency (>160W/in3 for 3.6kW 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.

Infineon's qualification plan for its GaN switches follows a dedicated approach well beyond Si standards (e.g. JEDEC) thereby setting the next level of wide bandgap quality. Application profiles (incl. most stringent and challenging applications requiring +15 years lifetime, e.g. server / telecom) are an integral part of the qualification. Failure models - based on accelerated test conditions - ensure that in the field a target lifetime and quality are met.

GaN EiceDRIVER™ ICs - Key Features & Benefits (Single-Channel Galvanically-isolated Gate Drivers for Enhancement Mode GaN HEMTs)

Every high-voltage GaN switch needs a dedicated driver IC to benefit from:

  • negative gate-driver voltage -> protection against spurious turn-on
  • two off-voltage levels -> least dead-time losses
  • excellent timing accuracy -> best system efficiency
  • constant switching transients -> least R&D effort
  • best robustness
  • reduced driver complexity and no need of customized drivers

High Voltage GaN Driving

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™ 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.
