Power Integrations, the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced that its automotive-qualified InnoSwitch™3-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 InnoSwitch3-AQ family 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. Edward Ong, Senior Product Marketing Manager at Power Integrations said: “New 400 V system designs for electric vehicles require higher operating voltages to account for fault conditions and transients.
