Power Integrations announces further support for EV designs Power Integrations has said that its automotive-qualified InnoSwitch3-AQ flyback switcher IC family is now available with a member rated to 900 V, providing greater headroom for 400 V and 800 V electric vehicle inverter, battery management and climate control applications. The family of devices combines primary and secondary controllers plus safety-rated feedback circuitry into a single IC. This allows accurate output voltage regulation, low component count and configuration options for operation over the ultra-wide input voltage range of 30 V to 1200 V. Commenting Edward Ong, Senior Product Marketing Manager at Power Integrations said, âNew 400 V system designs for electric vehicles require higher operating voltages to account for fault conditions and transients. The new 900 V INN3996CQ ICs provide plenty of voltage headroom and meet the Automotive Electronics Council strict requirements for qualification ensuring safe and reliable operation in the demanding automotive application. Using a StackFET approach, the new device is suitable for 900 V and greater bus designs.â
