Infineon Technologies AG has an efficient CoolGaNTM series of devices, which has been expanded with two additions: the CoolGaN 400 V device and the CoolGaN 600 V device. All the CoolGaN family products fulfill the JEDEC standards. Both the preceding devices can be presently ordered. In February 2020, the evaluation board EVAL_AUDAMP24 is expected to be available.
The features of CoolGaN 400 V device (IGT40R070D1 E8220) is suitable for premium HiFi audio systems where end users want every detail of their high-resolution soundtracks, a good substitute for bulky linear or tube amplifiers and ability to render excellent listening experience to the listening fans. It has enablement of smoother switching and more linear class D output stage because of low or linear Coss, zero Qrr, and normally-off switch. The ideal class D audio amplifiers provide zero percent distortion and 100 percent efficiency. Design simplification is attained by pairing with an HSOF-8-3 (TO-leadless) package with a famous class D controller (IRS20957STRPBF) in an evaluation board
The CoolGaN 600 V device (IGLD60R190D1) enables performance enhancement and cost optimization for low-power and mid-power applications and having a usage in low-power SMPS and Telecom rectifiers. It is having an extension with a new 190 mΩ, industrial-grade HEMT. Compatible with any consumer and industrial application with an optimized cost to decrease the technology entry barrier and support for easy design with a standardized DFN 8×8 packaging and matching driver ICs from the GaN EiceDRIVERTM series
The switching characteristics of the switching device impair power loss and linearity. The CoolGaN family breaks across the technology barrier by the introduction of zero reverse recovery charge in the body diode and infinitesimal, linear input and output capacitances. The result is that the end-users have a wider and natural soundstage audio experience.
