NCL30030 Datasheet | onsemi

features necessary for building a robust and pact PFC stage while minimizing the number of external ponents. The quasi- resonant current- mode flyback stage features a proprietary valley- lockout circuitry, ensuring stable valley switching. This system works down to the 4th valley and toggles to a frequency foldback mode with a minimum frequency clamp beyond the 4th valley to eliminate audible noise. Skip mode operation allows excellent efficiency in light load conditions while consuming very low standby power consumption. mon General Features - Wide VCC Range from 9 V to 30 V with Built- in Overvoltage Protection - High- Voltage Startup Circuit - Integrated High- Voltage Brown- Out Detector - Fault Input for Severe Fault Conditions, NTC patible (Latch and Auto- Recovery Options) - 0.5 A / 0.8 A Source / Sink Gate Drivers - Internal Temperature Shutdown .onsemi.
