Description
The NV9510/12 IC family are HFQR Flyback controllers that enable high-frequency operation, wide VDD range, highvoltage start-up, and multi-mode operation. The NV9510 IC family includes short-circuit, over-temperature and LPS protection features to make the devices well suited for a bestin-class reliable system with ultra-low part-count BOM. The devices, with less than 20m W standby power, are optimized for high power density AC/DC power supplies. The NV9510 IC family supports a wide VDD operating range to cover variable output applications with USB-PD/PPS and DP/DN protocol munication. Small footprint SOIC-10 packaging enables designers to achieve simple, quick and reliable solutions. Navitas’ Ga N IC and controller technologies enable high...
