NCP1027ATXGEVB: 10 W Standby ATX Evaluation Board

Evaluation/Development Tool Description
The NCP1027 offers a new solution targeting output power levels from a few watts up to 15 W in a universal mains flyback application. Proproety high-voltage technology lets us include a power MOSFET together with a start up current source, all directly connected to the bulk capacitor. To prevent lethal runaway in low input voltage condition, an adjutable brown-out circuitry blocks the activity until a sufficient input level is reached. Current-mode operation together with an adjustable ramp compensation offers superior performance in universal mains applications.
Protection wise, a timer detects an overload or a short circuit and stops all operations, ensuring a safe auto-recovery, low duty cycle burst operation. Intergrated, auto-recovery, over voltage protection permenatley monitors the VCC level and temporarily shuts down the driving pulses in case of an unexpected feedback loop runaway.
Finally, a great RDSon figure makes the circuit an excellent choice for standby/auxiliary offline power supplies or application requiring higher output power levels.
