Product Overview

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.
  • Skip-cycle operation at low peak currents
  • Internal current source for clean and lossless startup sequence
  • Auto-recovery output short circuit protection with timer-based detection
  • Auto-recovery overvoltage protection with auxiliary winding operation
  • Programmable brown-out input for low input voltage detection
  • Programmable over power protection
  • Input to permanently latch-OFF the part
  • Internal frequency jittering for improved EMI signature
  • 80% Extended duty cycle operation
  • 85mW at 265VAC No-load input standby power
  • 500mW Loaded, input power of 715mW at 230VAC
  • 65 and 100kHz Current-mode fixed frequency operation
  • 800mA Fixed peak current
