APEC 2023 Power+Integrations (NASDAQ: POWI), the leader in high-voltage integrated circuits (ICs) for energy-efficient power conversion, today announced a 900-volt gallium-nitride (GaN) extension to the company’s InnoSwitch3™ family of flyback switcher ICs. 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.
