The new ICs, which feature the company’s proprietary PowiGaN™ technology, deliver up to 100 watts with better than 93 percent efficiency, eliminating the need for heat sinks and streamlining design of space-challenged applications. InnoSwitch3 designs also offer exceptional light-load efficiency making them ideal for providing auxiliary power in electric vehicles during low-power sleep modes. The AEC-Q100-qualified InnoSwitch3-AQ family is particularly suitable for EVs based on 400-volt bus systems where the 900-volt PowiGaN switch provides more power and increased design margin―required for 12-volt battery-replacement systems―with enhanced efficiency over silicon-based converters.\nThis press release features multimedia.

The 900-volt PowiGaN switch is extremely beneficial because it easily accommodates inductive noise spikes, yet it can operate from as low as 30 VDC, enabling systems to meet functional safety active discharge requirements. The extra power delivered by our GaN technology matches the increasing power demands of EV manufacturers, moreover, efficiency in power conversion―even in auxiliary systems―is important for both range extension and thermal management.”\n\nIn the industrial space, extra power and increased efficiency are extremely advantageous in applications such as appliances, three-phase motors and auxiliary power supply units (PSUs) in servers. The new 900-volt parts are pin-for-pin compatible with existing 725-volt and 750-volt ...
