NCP1028 Datasheet | onsemi

High-Voltage Switcher for Medium Power Offline SMPS Featuring Low Standby Power The NCP1028 offers a new solution targeting output power levels from a few watts up to 15 W in a universal mains flyback application. Our proprietary high- voltage technology lets us include a power MOSFET together with a startup current source, all directly connected to the bulk capacitor. To prevent lethal runaway in low input voltage conditions, an adjustable brown- out circuitry blocks the activity until sufficient input level is reached. Current- mode operation together with an adjustable ramp pensation offers superior performance in universal mains applications. Furthermore, an Over Power...
