Key Features

  • Built-in 700 V MOSFET: With an RDS(ON) of 4.8 Ω for the NCP1076uz version, ensuring high efficiency and reliability.
  • Current-mode Fixed Frequency Operation: Supports frequencies of 65 kHz, 100 kHz, and 130 kHz.
  • Soft-start and Frequency Jittering: Reduces electromagnetic interference (EMI) and ensures smooth startup.
  • Short-circuit Protection and Skip-cycle: Enhances reliability by preventing damage from short circuits and reducing standby consumption.
  • Dynamic Self-Supply (DSS): Eliminates the need for an auxiliary winding, providing supply voltage via an internal high-voltage current source.
  • Line Detection and Brown-out/AC Line Over-Voltage Protection: Prevents operation at too low or too high AC input voltages, ensuring safe and stable operation.
  • Over-power Protection (OPP): Compensates for internal delays in high input voltage conditions to optimize maximum output current capability.
  • Temperature Shutdown and Hysteresis: Protects the device from overheating with a temperature shutdown at 150°C and a hysteresis of 20°C.

Applications
