NCP1027P065G

IC, MONOLITHIC SWITCHER, 65KHZ.

The NCP1027P065G is a High-voltage Switcher for medium power offline Switched Mode Power Supply (SMPS) featuring low standby power. 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. Furthermore, an over power protection pin brings the ability to precisely compensate all internal delays in high input voltage conditions and optimize the maximum output current capability. Protection wise, a timer detects an overload or short-circuits and stops all operations, ensuring a safe auto-recovery, low duty cycle burst operation. An integrated, auto-recovery, overvoltage protection permanently monitors the VCC level and temporarily shuts down the driving pulses in case of an unexpected feedback loop runaway.
