AC-DC Off-Line Regulators, ON Semiconductor

The Offline, AC-DC switching regulators, feature control in current and voltage mode. The NCP105x series are gated oscillator power switching regulators. Applications include robust and highly efficient power supplies, essentially Switch Mode Power Supply (SMPS).

The NCP1027 offers a new solution targeting output power levels from a few watts up to 15W 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.
